[0048] A chemical index detection method of a polymeric ferric chloride water purifying agent, comprising the following steps: Step one: sample addition: add the polymeric ferric chloride solution into the transparent detection cylinder 2; Step two: nitrogen addition: add nitrogen into the transparent detection cylinder 2 through the gas inlet pipe 23 to isolate the polymeric ferric chloride solution from the air; Step three: positioning of the transparent detection cylinder 2: position the transparent detection cylinder 2 on the detection positioning table 1 through the positioning groove 11; Step four: addition of detection reagent: add different detection reagents through the rotation of the second rotating disc 5.
[0049] In addition, during detection, the reducing agent is added through the syringe 8. The reducing agent can be selected according to actual needs. The trivalent iron ion is reduced to divalent iron ion through the reducing agent. The sodium diphenylamine sulfonate solution is used as an indicator, and the potassium dichromate standard solution is used for titration. That is, the sodium diphenylamine sulfonate solution is added into the transparent detection cylinder 2 through the syringe 8, and then the potassium dichromate standard solution is added through the syringe 8. During titration, the color of the solution gradually changes from green to purple red. When the color change is obvious and stable, it is the end point of titration. Then, the volume of the potassium dichromate standard solution consumed in titration is recorded, and the iron content is calculated according to the titration data. The specific calculation formula is: Iron content = C × V × M ÷ m in: C: Concentration of potassium dichromate standard solution (mol / L); V: Volume of potassium dichromate standard solution consumed in the titration (L); M: Molar mass of iron (55.85 g / mol); m: Sample mass (g).
[0050] In specific operation, polyferric chloride solution is added to the transparent detection cylinder 2. Then, nitrogen is added to the transparent detection cylinder 2 through a nitrogen cylinder, that is, the inlet pipe 23 is connected to the nitrogen cylinder. As the nitrogen enters the transparent detection cylinder 2, it will expel air from the exhaust pipe 33. Nitrogen is introduced for a certain period of time to ensure that all the air in the transparent detection cylinder 2 is expelled. Then, it is positioned on the detection positioning stage 1. At this time, the detection reagent can be added. Pulling the support bar 73 will cause the locking support column 72 to disengage from the locking plate. 57. The upper locking hole 58 is then pushed down onto the support plate 6 until the locking post 72 aligns with the lower locking hole 58 of the locking plate 57. The support bar 73 is then released, allowing the locking post 72 to be inserted into the lower locking hole 58 of the locking plate 57, thus fixing the support plate 6. As the support plate 6 moves downward, the anti-rotation post 64 will be inserted into the anti-rotation locking hole 32, thereby fixing the cylinder cover 3 and preventing it from rotating under external force, ensuring the sealing of the transparent detection cylinder 2. Furthermore, as... The downward movement of the support plate 6 will cause the injection tube 81 to contact the upper end face of the sealing rod 47. Under the action of the injection tube 81, the sealing rod 47 will be pushed downward, and the injection tube 81 will be inserted into the connecting channel 46. The sealing block 48 will be disengaged from the mating sleeve 44. At this time, the injection hole 82 is between the two connecting strips 43. When the injection tube 81 reaches the working position, the injection plug rod 86 is pushed downward, which will drive the injection plug plate 87 to move downward, so that the test reagent in the syringe 8 can be sprayed out from the injection hole 82 into the transparent test tube 2, realizing sealed addition. After one reagent is added, the support plate 6 is unlocked and moved upward. The sealing rod 47 is reset under the action of the first spring 49, and the connecting channel 46 is sealed again. Then, the second rotating disk 5 is rotated to rotate another syringe 8 to the top of the connecting channel 46. The same operation is performed to add another test reagent. In addition, during the addition process, the stirring column 4 can be rotated by the first rotating disk 45, so that the stirring plate 41 can stir the solution to ensure that the reaction is complete.
[0051] When adding the detection reagent into the syringe 8, the syringe 8 is removed, that is, the syringe 8 is smoothly removed by using a certain force to overcome the adsorption force between the first adsorption magnet 692 and the second adsorption magnet 85. After the syringe 8 is removed, the adsorption of the detection reagent is performed through the injection hole 82. After the adsorption of the detection reagent is completed, the syringe 8 is installed to the support table 6. The syringe 8 is fixed by the adsorption force between the first adsorption magnet 692 and the second adsorption magnet 85. The operation is simple, convenient and fast. The syringe 8 is supported by the support table 6, so that the instability of the handheld syringe 8 can be avoided. The adding operation of the detection reagent and the stirring operation of the solution are facilitated.
