Heavy metal removal method from mineral drug

Abstract

The invention discloses a process for processing mineral medicaments such as cinnabar, orpiment, native copper, magnetite, and reddle, especially the method for dissolving and removing hazardous materials in the medicaments, which comprises processing the minerals with bacteria, dissolving the minerals insoluble to water into aqueous solutions under the action of bacteria, then removing unwanted ions in the solution through chemical or physical methods.

Description

Dissolving method of mineral medicine technical field The present invention relates to a treatment method for traditional Chinese medicine ore medicine (referring to mineral medicine in traditional Chinese medicine and other ethnic medicines), more precisely, it is a kind of treatment method for using bacteria to treat insoluble mineral medicine, such as: cinnabar, realgar, natural copper , Magnet, substitute ocher, etc., become a method of dissolving soluble components into a solution. Background technique In addition to a large number of herbal medicines and animal medicines, the Pharmacopoeia of Chinese Medicine also contains many mineral medicines, such as: cinnabar, realgar, natural copper, magnet, ochre, etc. In Chinese medicine practice, the unique effects of these drugs are used to treat various diseases in combination with other drugs. However, due to the excessive amount of heavy metal harmful ingredients contained in mineral medicines, its use is subject to som...

Problems solved by technology

But on the other hand, so far in the production of traditional Chinese medicine, there is no better treatment method except that the traditional Chinese medicine processing method is still used to process mineral medicine.

The mineral traditional Chinese medicine processing methods stipulated in the Chinese Pharmacopoeia, such as: burning moxibustion, water flying, forging, and vinegar quenching, are not only time-consuming, laborious, and energy-consuming, but also produce waste gas and wastewater pollution. More importantly, the use of such methods is not only ineffective. Dissolving mineral traditional Chinese medicine, let alone quantitatively control the content of active ingredients in the medicine

Theoretically speaking, mineral traditional Chinese medicine can be dissolved by using chemical methods, but chemical methods often require harsh conditions such as aqua regia, and it is difficult to retain the necessary active ingredients in mineral medicines, thus losing the therapeutic effect of traditional Chinese medicine; on the other hand, using pure chemical methods Drug processing may also introduce components that the drug itself does not have, and even introduce toxic and highly toxic components into the drug. Remove these extra ingredients

In addition, these traditional Chinese medicine mineral medicines are used in medical practice by themselves or in combination with other medicines to treat diseases. Because the mineral medicines are insoluble in water, there are the following defects in application. First, the active ingredients cannot fully exert their effects; Second, the amount of mineral medicine used is relatively large, and the content of heavy metals and arsenic exceeds the standard; third, mineral medicine is difficult to dissolve in water, so its use is subject to some restrictions, such as difficult to apply in the prescription of injection medicine, etc.

Fourth, it is impossible to quantitatively control the content of active ingredients and harmful substances in drugs
