Description
technical field [0001] The invention belongs to the technical field of drug detection, and specifically discloses a method and a device for detecting lead metal in drugs. Background technique [0002] Heavy metals refer to metal impurities that can react with thioacetamide or sodium sulfide to develop color under experimental conditions. After heavy metals enter the human body, they can destroy the protein properties of the human body and seriously affect the health of the human body. In the production process of medicines, it is inevitable that some heavy metals will be mixed, such as lead, zinc, mercury, cadmium and so on. There are many chances of encountering lead in production, and lead is easy to accumulate in the human body and cause poisoning, so lead is used as the representative in the inspection. The appendix of the first supplement of the Chinese Pharmacopoeia 2010 stipulates three detection methods. There are existing technologies According to these three meth...
