Problems solved by technology

However, the current situation of heavy metal pollution in Chinese herbal medicines is very serious in my country. Especially in the past 30 years, with the rapid development of urbanization and industrialization, a large amount of untreated domestic sewage and industrial wastes have been discharged randomly, as well as unreasonable use of chemical fertilizers and pesticides. The phenomenon of excessive heavy metals in Chinese medicinal materials is serious, and the quality continues to decline. The excessive content of heavy metals in Chinese medicinal materials has become a problem that cannot be ignored
[0003] Heavy metal elements may cause lesions in various parts of the body, including the skin, nervous system, vascular system, etc., and even lead to cancer. At present, countries and regional organizations in the world have implemented strict control on heavy metal pollution, and the drinking of traditional Chinese medicine is One of the indispensable means in the treatment process, so it is very important to remove heavy metals in traditional Chinese medicine drinking, but the existing removal process for heavy metal residues in traditional Chinese medicine has poor effect, and the removed traditional Chinese medicine still contains more Heavy metal ion residues, so it is necessary to replace a more effective process for removing heavy metal residues

Abstract

The invention discloses a process for effectively removing heavy metal residues in traditional Chinese medicines. The process comprises the following steps of: adding the traditional Chinese medicinesinto a cooking boiler, adding tap water, heating to boil, filtering out filter residues by using a filter screen, and putting a filtrate A into a container for retaining; putting the filter residuesinto the cooking boiler again, and repeating the above steps for multiple times to obtain a filtrate B, a filtrate C and a filtrate D; combining the filtrates, adding the combined filtrate into a stirring container, adding mass snake-cage resin, and filtering by using a molecular sieve to obtain a filtrate E; adding the obtained filtrate E into a centrifugal machine, adding modified chitosan chelate resin, and performing centrifugal treatment to separate upper-layer liquid medicine F and precipitate G; and filtering the precipitate G by using a filter screen, and filtering the precipitate G and the upper-layer liquid medicine F again by using activated carbon to obtain a liquid medicine J. According to the process for effectively removing the heavy metal residues in the traditional Chinesemedicines, the heavy metals in the liquid medicine are removed as much as possible.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine processing, and in particular relates to a process for effectively removing heavy metal residues in traditional Chinese medicine. Background technique [0002] Traditional Chinese medicine is the quintessence of our country's civilization for thousands of years, and has made outstanding contributions to the reproduction of the Chinese nation. However, the current situation of heavy metal pollution in Chinese herbal medicines is very serious in my country. Especially in the past 30 years, with the rapid development of urbanization and industrialization, a large amount of untreated domestic sewage and industrial wastes have been discharged randomly, as well as unreasonable use of chemical fertilizers and pesticides.
