Detecting method for limited residual quantity of heavy metals in traditional Chinese medicinal material or traditional Chinese medicinal decoction piece

Abstract

The invention discloses a detecting method for limited residual quantity of heavy metals in a traditional Chinese medicinal material or a traditional Chinese medicinal decoction piece. The detection is realized by an intelligent detecting system. The detecting method comprises the following steps: S1, detecting information security; S2, evaluating the information security; S3, displaying and alarming the information security. According to the detecting method disclosed by the invention, the intelligent system replaces people for conducting security detection on residual heavy metals of the traditional Chinese medicinal material. By use of the system and the method, the interference of human subjective factors can be eliminated, detection results varying from person to person are avoided, people are liberated from strenuous labor, the precision can be improved, and guarantee is provided for the security of the traditional Chinese medicinal material. The detecting method disclosed by the invention has the capabilities of detecting ten heavy metal elements at the same time: copper, chromium, germanium, lead, arsenic, selenium, cadmium, mercury, manganese and zinc in edible mushrooms.
