Problems solved by technology

Foreign countries have also used cation exchange columns and activated carbon to remove pesticide residues. Experiments have proved that the combined use of the two is better than the use of organic activated carbon alone, but at the same time there are disadvantages such as less processing capacity and complicated instrument use.

Description

technical field [0001] The invention relates to the technical field of cleaning Chinese medicinal materials, in particular to a device and method for degrading pesticide residues in Chinese medicinal materials. technical background [0002] Traditional Chinese medicine is a precious cultural heritage of our country, and it is a magic weapon for the Chinese nation to prevent and treat diseases, restore health care, and reproduce. But now, due to the uncertainty of the active ingredients of Chinese medicinal materials and the excessive residues of harmful substances such as pesticides and heavy metals, it has become two major obstacles for Chinese medicine to enter the world. The reasons for pesticide pollution in Chinese herbal medicines are as follows: 1. The growers of Chinese herbal medicines lack basic plant protection knowledge, and the phenomenon of abusing pesticides is very serious; Soil, water and air pollution, etc.; 3. The pesticide pollution caused during the har...
