Device for detecting solid-liquid solubility by laser intensity

Abstract

The invention relates to a device for detecting solid-liquid solubility by laser intensity. According to the device, a thermostatic circulating water bath and a laser emitter are connected with a power supply by conductive wires; the thermostatic circulating water bath is communicated with a glass jacket bottle; magnetons are arranged in a test sample bottle in the glass jacket bottle; a magnetic stirrer is arranged at the bottom of the glass jacket bottle; a sample loading injector extending into the test sample bottle, and a contact-type temperature sensor are arranged on a rubber plug at the top of the glass jacket bottle; the laser emitter and a laser receiver are arranged at the both sides of the glass jacket bottle, respectively; the laser receiver and the temperature sensor are connected with a digital light intensity display by conductive wires, respectively; the digital light intensity display is connected with a computer by a conductive wire. The device disclosed by the invention overcomes the problems of high error, instability and poor repeatability generated by observation with naked eyes during the process of measuring solubility by a traditional turbidity point method, realizes quantitative and continuous injection of a solvent, and solves the problem of attachment of a sample to the wall of a container during sample injection.

Description

technical field [0001] The invention belongs to the technical field of solution phase equilibrium research, in particular to a device for detecting solid-liquid solubility by using laser light intensity. Background technique [0002] Phase chemistry is one of the important applications of thermodynamics in chemistry. Extracting materials from natural salts through smelting, extraction, distillation, coagulation and other processes, synthesizing industrial products, producing daily necessities, etc., all require knowledge of phase chemistry. Therefore, it is of great significance to study the phase equilibrium of multiphase systems in the scientific research and production of chemistry and chemical industry, and a large part of the research on phase equilibrium depends on the determination of solid-liquid solubility. [0003] Traditional solubility determination methods have great limitations, and the common solubility determination methods mainly include equilibrium method ...

AI Technical Summary

Problems solved by technology

[0006] At present, the turbidity point measurement devices used in the experiment all use condenser tubes and large-volume sample bottles. The experimental equipment is complicated, and the large amount of samples used leads to serious solvent volatilization, which reduces the accuracy of the experiment.
