Problems solved by technology

But on the other hand, so far in the traditional Chinese medicine preparation industry, there is no better treatment method except that the traditional Chinese medicine processing method is still used to process mineral medicines.
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. Removal of heavy metals in medicines, let alone quantitative control of the content of active ingredients in medicines
Theoretically speaking, the use of chemical separation technology can completely remove the heavy metal components in the relevant mineral medicines, but these methods are difficult to retain the necessary active ingredients and characters in the mineral medicines, thus losing the therapeutic effect of traditional Chinese medicine; on the other hand, using The pure chemical method of drug treatment may also introduce components that the drug itself does not have, and even introduce toxic and highly toxic components into the drug. It is also difficult to remove these extra ingredients

Embodiment 1

[0016] The processed mineral Chinese medicines are realgar and cinnabar.

[0017] Crush the mineral medicine to about 100 meshes, and then carry out spectrometry on the mineral medicine powder to understand its specific composition.

[0018] Mineral fine powder is then added to the treatment solution according to mineral powder: the treatment solution is a ratio (weight ratio) of 1: 10, the treatment solution wherein contains the basic components of bacterial strains and 9K medium [9K medium basically consists of: each 1000 ml culture medium containing (NH 4 ) 2 SO 4 3.0g, KCl0.1g, K 2 HPO 4 0.5g, MgSO 4 ·7H 2 O0.5g, Ca(NO 3 ) 2 0.01g, FeSO 4 ·7H 2 [044.7g], wherein the strains used are: Thiobacillus ferrooxidans, Thiobacillus thiooxidans and Leptospira ferrooxidans are combined in equal proportions, and the inoculum size is 10%.

[0019] After stirring the ore powder and the treatment solution evenly, adjust the pH of the system to 1.5 with 0.1N dilute sulfuric aci...

Embodiment 2

[0028] The processed mineral Chinese medicines are realgar and cinnabar.

[0029] Mineral medicine is pulverized into different particle sizes, realgar and cinnabar are processed according to the processing method of Example 1, the results are shown in Table 3

[0030] Traditional Chinese Medicine Mineral Medicine

Embodiment 3

[0032] The processed mineral Chinese medicines are realgar and cinnabar.

[0033] Mineral medicine was crushed into 80 meshes, mineral powder and treatment solution in the system were added in different proportions, and realgar and cinnabar were treated according to the treatment method of Example 1. The results are shown in Table 4.

Abstract

The present invention relates to medicine material treating method, and method of removing harmful heavy metals and arsenic from mineral Chinese medicinal materials, such as cinnabar, realgar, native copper, magnet, hematite, etc. The method includes bacteria treatment of mineral Chinese medicinal materials to convert the water insoluble components in the mineral Chinese medicinal materials into water soluble components, and subsequent specific chemical deposition reaction, membrane dialysis and / or other steps to eliminate harmful ions in the solution.

Description

technical field [0001] The invention relates to a treatment method for raw medicine, more precisely, a method for removing harmful heavy metals and arsenic from mineral medicines in traditional Chinese medicine, such as cinnabar, realgar, natural copper, magnetite, ochre, and the like. Background technique [0002] 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 some restrictions, or certain negative effects are produced. Especially since the 1980s, the international community has reacted strongly to heavy metals in Chinese patent medicines exported by my coun...
