Read： 612 Time：7months ago Source：Transform the World with Simplicity

Chloroplatinic acid solution configuration is a common operation in chemical experiments, and the correct configuration method will directly affect the quality and performance of the catalyst. The following will introduce some precautions for everyone, hoping to help you scientifically and rationally configure chloroplatinic acid solution.

first, raw material preparation. Chloroplatinic acid is an expensive compound, so make sure that the raw materials are sufficient and the amount is controlled before the solution is configured. At the same time, we should also pay attention to the storage conditions of raw materials to avoid moisture, oxidation and other conditions affecting the quality of raw materials.

second, solvent selection. In the preparation of chloroplatinic acid solution, the choice of solvent is crucial. In general, ethanol, methanol, ethylene glycol and other organic solvents are commonly used in the configuration of solvents, but different experimental purposes need to choose different solvents. Should be based on the experimental requirements, the performance of the catalyst and other factors to make a reasonable choice.

third, pay attention to operation. When configuring the chloroplatinic acid solution, you need to pay attention to the details of the operation.

should pay attention to the control of the dissolution temperature and stirring speed, so as not to cause insufficient dissolution or excessive volatilization of the solution.

should pay attention to the stirring time and the storage conditions of the solution to avoid affecting the quality of the catalyst.

fourth, safety protection. Chloroplatinic acid is a toxic compound, the operation should strictly abide by the safety procedures, wear protective equipment, to ensure personal safety. At the same time, the solution should be configured to avoid the generation of toxic gases, and the operation should be carried out under good ventilation.

fifth, quality control. After the chloroplatinic acid solution is configured, the concentration and quality of the solution should be tested to ensure that it meets the experimental requirements. The content of chloroplatinic acid in the solution can be determined by ultraviolet-visible spectroscopy, atomic absorption spectroscopy and other means to ensure the quality of the catalyst. The configuration of

chloroplatinic acid solution requires not only scientific and reasonable methods, but also rigorous operation and quality control. It is hoped that the introduction of this article can provide some help for everyone in the experiment and help researchers prepare high-quality catalysts.
