Abstract

The invention discloses equipment for realizing automatic titration by adopting temperature. The equipment comprises a workbench, a support frame, a support plate, a test bottle, a temperature sensor, a motor, a rotating shaft, a plurality of stirring rods, two liquid inlet assemblies, a burette, an infusion tube and a control host; the liquid inlet assembly comprises a fixing frame, a solvent bottle, a connecting pipe and an electromagnetic valve; during detection, the electromagnetic valve communicated with the infusion tube is opened through the control host, so that a solvent to be detected flows into the test bottle; then the electromagnetic valve communicated with the burette is opened, the standard reagent is dropwise added into the test bottle, the motor is started to enable the plurality of stirring rods to rotate, the solvent to be detected and the standard reagent fully react, heat is generated in the reaction process, heat change is monitored by the temperature sensor, and data is sent to the control host; and the concentration of the solvent to be detected can be calculated by analyzing the heat change in the reaction process, and the detection is not influenced by the turbidity and concentration of the solvent to be detected.

Description

technical field [0001] The invention relates to the technical field of chemical analysis equipment, in particular to an equipment that uses temperature to realize automatic titration. Background technique [0002] Titration analysis is a kind of chemical analysis. A standard reagent whose exact concentration is known is added dropwise to the solution of the tested substance until the chemical reaction is completely stopped, so as to calculate the content of the tested component. The existing titration equipment mainly uses two methods to judge the titration end point. One is to indicate the titration end point through the change of the indicator color, but if the solution to be measured is turbid, it is more difficult to indicate the end point; the other is to judge the end point according to the change of the indicator electrode potential Determine the end point of the titration. Although this method can be used for the titration of colored or turbid solutions, the electrod...
