Abstract
The invention belongs to sample detection technical fields, and in particular to Chinese medicine quality is quickly defined the level test paper and preparation method thereof.Test paper of the present invention is only made of substrate and developing paper two parts, and structurally and operationally all very simple, this test paper can be used for quickly detecting lead, cadmium, mercury, 4 kinds of elements of arsenic and pesticide residue content in Chinese herbal medicine in 0.5-1min;By visual observation you can get it accurate quantitative detection conclusion, it is not required to be shown with expensive instrument, it is easy to operate, it can be grasped without specialized training;Production cost is low, and accuracy is high, reproducible, is extremely suitable for the detection real-time, quickly of Chinese herbal medicine scene and monitoring.
Description
Technical field
Invention belongs to sample detection technical field, and in particular to Chinese medicine quality is quickly defined the level test paper and preparation method thereof.
Background technique
Heavy metal is a key factor for influencing Chinese medicine quality, and harmful heavy metal element refers mainly in Chinese medicine
Lead, cadmium, mercury, copper, chromium etc., arsenic are also one of harmful element in Chinese medicine as a kind of metalloid element, routinely monitor have lead,
Cadmium, mercury and four kinds of arsenic.
Pesticide (Pesticides) is primarily referred to as endangering harmful organism (such as pest, evil of agriculture forest and husbandry production for preventing and treating
Mite, nematode, pathogen, weeds and muroid etc.) and coordinate plant growth chemicals, mainly include organo-chlorine pesticide, organic
Several major class such as phosphorus pesticide, carbamate chemicals for agriculture.Wherein, organophosphorus pesticide, carbamate chemicals for agriculture can inhibit significantly
The activity of acetylcholinesterase, long-term intake can cause to damage to the nervous system of people and animals, thus by multinational disabling or limit the use of.
The control of Chinese medicine quality is all a problem to be solved all the time, in the quality control of Chinese medicine, is established fast
Speed, conveniently, accurate detection method it is significant.Test paper detection is a kind of quick detection means, currently used for Chinese medicine toxicity
