[0029] S2, one of the placement boxes 1 is used for calculating the total available oxygen of the sample, the carrier sheet 10 in one of the determination tanks 2 in the placement box 1 is loaded with a sample for the test specimen, and the carrier sheet in the other determination tank 2 is empty of the sample for the blank experiment; isopropanol solution, glacial acetic acid solution and a newly configured saturated potassium iodide solution are added to the two determination tanks 2 from the position of the nozzle 2 5, and the mixture is shaken by the shaking mechanism 3 and then placed in the dark, starch indicator is added, and then titrated with a sodium thiosulfate standard titration solution until it is colorless, and the mass fraction of the total available oxygen of the sample is calculated;

[0030] The mass fraction of effective oxygen is W1 and is calculated according to the following formula:

[0031] W1=(V1-V0)×c×M / (2×1000×m)

[0032] Where:

[0033] V1—the volume of the standard sodium thiosulfate titration solution used for the sample, mL;

[0035] c—concentration of sodium thiosulfate standard titration solution, mol / L;

[0036] M—molar mass of oxygen, g / mol (M=16);

[0037] m - mass of the sample, g;

[0040] W2=(V1-V0)×c×M / (2×1000×m)

[0041] Where:

[0042] V1—the volume of the standard sodium thiosulfate titration solution used for the sample, mL;

[0048] The method for determining the content of hydrogen peroxide in an organic ketone peroxide has the advantages of simple operation, time-saving and labor-saving, and low equipment requirements, and meets the industrial analysis requirements of chemical enterprises; and because the measuring tanks 2 for the sample and the blank experiment are placed in the same placing box 1 and the same shaking mechanism 3 is used for the shaking operation, the influence of external environmental factors and the influence of manual shaking on the processing time operation mode are effectively reduced, and the residual influence of pouring after weighing is effectively avoided by directly weighing the carrier sheet 10 and then putting it in, thereby further improving the accuracy and convenience of determining the content of hydrogen peroxide in the organic ketone peroxide.

[0049] Embodiment 2: Embodiment 2 includes all structures and methods of Embodiment 1, with reference to Figure 1-Figure 9 A device for determining the content of hydrogen peroxide in organic ketone peroxide. On the basis of Example 1, a box cover 101 made of transparent material is arranged at one end of a placement box 1, and a cover frame 19 is detachably connected to the top of the placement box 1. The end faces of the cover frame 19 corresponding to the box cover 101 are made of transparent material. The cover frame 19 is provided with a through hole corresponding to the position of the pipe mouth 4. During the process of adding a reagent, the cover frame 19 is opened for operation. When placed in the dark, the cover frame 19 is covered so that the two measuring tanks 2 in the placement box 1 are in the same chamber to reduce the influence of the external environment. During titration, the changes in the measuring tank 2 can be directly observed through the end face, further reducing the influence of external environmental factors and improving the accuracy of the measurement.

[0050] In the present invention, the shaking mechanism 3 is provided with two vacuum suction cups 11, and a connecting hose 111 extending outward is connected to the bottom of the vacuum suction cup 11. The vacuum suction cup 11 adsorbs and fixes the bottom end of the measuring tank 2. An arc-shaped connecting frame 12 is installed between the bottoms of the two vacuum suction cups 11. The connecting frame 12 is set to an arc-shaped structure that bends downward in the middle position. A gear groove 122 is opened on the top of the connecting frame 12. A motor 14 is installed at the bottom of the placement box 1. A gear 15 is installed on the output shaft of the motor 14. The gear 15 is meshed with the gear groove 122. Slide grooves 121 are opened on both sides of the connecting frame 12. Two mounting frames 13 are fixed to the bottom of the placement box 1. The top of the mounting frame 13 is in sliding contact with the two slide grooves 121, so that the connecting frame 12 and the vacuum suction cup 11 are supported by the two mounting frames 13, and the vacuum suction cup 11 and the bottom of the measuring tank 2 are supported by the vacuum suction cup 11. The adsorption allows the measuring cans 2 on both sides to be placed stably, and the reciprocating swing of the connecting frame 12 is achieved through the meshing between the gear 15 and the connecting frame 12, and the reciprocating rotation of the motor 14, so that the two measuring cans 2 in the placing box 1 are reciprocated along the connecting frame 12 to achieve the shaking operation; and through the slidable setting between the movable rod 7 and the sealing sleeve 602, during the reciprocating swinging process of the measuring cans 2, the fixed box 9 and the fixed frame 8 will carry the carrier sheet 10 with the deflection of the movable rod 7, and the fixed box 9, the fixed frame 8 and the carrier sheet 10 will be tilted due to the deflection, and will rotate around the circumferential direction of the movable rod 7 under the action of gravity, that is, the fixed box 9, the fixed frame 9 and the carrier sheet 10 move relative to the inner wall of the measuring can 2, thereby improving the rapid dispersion effect and uniform dispersion effect of the sample in the carrier sheet 10, thereby further improving the measurement efficiency and measurement effect.

[0051] In the present invention, two measuring tanks 2 are distributed at both ends of the placement box 1, and the second nozzle 5 and the third nozzle 6 are distributed at both sides of the measuring tank 2. The positions of the inner walls on both sides of the placement box 1 corresponding to the second nozzle 5 and the third nozzle 6 are provided with auxiliary stabilizing mechanisms 16. The auxiliary stabilizing mechanisms 16 are provided with a horizontally placed spring telescopic rod 163 and a horizontally placed stabilizing rod 164. The spring telescopic rod 163 is provided with a slidably connected cylinder and a round rod, and a spring 1 is connected inside the round rod and the cylinder. The stabilizing rod 164 is fixed to the end of the round rod away from the spring 1. The spring telescopic rod 163 extends horizontally from the inner wall of one side of the placement box 1 toward the measuring tank 2. The stabilizing rod 164 is vertically arranged with the spring telescopic rod 163. The bottom outer walls of the second nozzle 5 and the third nozzle 6 are in sliding contact with the corresponding stabilizing rod 164. In the normal placement state, the two vacuum suction cups 11 are horizontally arranged to make the two measuring tanks 2 vertically stable. When the measuring tank 2 is shaken back and forth, the bottom of the second pipe mouth 5 and the third pipe mouth 6 are in contact with the middle position of the corresponding stabilizing rod 164. During the reciprocating swinging of the measuring tank 2, when the second pipe mouth 5 and the third pipe mouth 6 are swung downward toward the end direction, one end of the stabilizing rod 164 can be pressed to deflect around the round rod or squeeze the round rod into the cylinder, so that the spring 1 is used to assist in stabilizing the round rod, the stabilizing rod 164 and the measuring tank 2, thereby improving the stability and safety of the measuring tank 2 during the shaking process. A positioning cylinder 161 is fixed to the inner wall of the placement box 1 below the cylinder, and a rotating rod 162 extending vertically upward is connected to the upper part of the positioning cylinder 161 through a torsion spring. The top of the rotating rod 162 is fixed to the bottom of the cylinder, and a through groove 18 is provided at the position corresponding to the side wall of the placement box 1 and the spring telescopic rod 163 and the stabilizing rod 164, so that the spring telescopic rod 163 and the stabilizing rod 164 can be rotated outward from the through groove 18 position to take out the measuring tank 2 for cleaning or replacement.

[0052] In the present invention, a guide mechanism 17 is provided at a position corresponding to the ball head at the end of the movable rod 7 and the inner wall of the placement box 1. The guide mechanism 17 is provided with a guide rod 174 of an arc structure. The guide rod 174 is arranged in parallel with the connecting frame 12 in the horizontal direction. The guide rod 174 is arranged in an arc structure that arches downward in the middle position. The bottom of the ball head is in sliding contact with the outer wall of the top of the guide rod 174. When the measuring tank 2 is swung, especially when it is swung downward, the guide rod 174 limits the position of the ball head, so that the ball head moves upward relative to the measuring tank 2. The second rotating rod 172 is connected to the upper side of the positioning cylinder 171 by a torsion spring and extends vertically upward. The top of the second rotating rod 172 is fixed with a horizontally placed spring telescopic rod 173. The end of the telescopic rod 173 is fixed to a guide rod 174. The guide rod 174 is located above the placement box 1, so that the guide rod 174 can be turned out to take out the measuring tank 2.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
