Problems solved by technology

Gas chromatography requires special derivatization or cracking of the sample before detection, and the operation is relatively complicated.
The detection results of mass spectrometry are accurate, reliable and reproducible, but the equipment is expensive, the technical content is high, and it is difficult to popularize and apply
The application of capillary electrophoresis technology in the detection of paraquat poisoning is still relatively small, and the analysis and detection results are not ideal, which needs further research. Due to the strong polarity and high boiling point of paraquat, the HPLC analysis method is the most reported, so HPLC Chromatography has always been the preferred detection instrument for many researchers to determine paraquat
Although UV-Vis spectrophotometry has low sensitivity and many interference factors
Although the "paraquat detection technology" currently used clinically can be qualitative and quantitative, the technology is very complicated, the detection time is long, and the cost is high

Description

technical field [0001] The invention relates to a detection test paper, which belongs to the field of analytical chemistry, in particular to a preparation method of a reduced-type rapid detection paraquat test paper, which is used in the rapid detection of paraquat. Background technique [0002] Paraquat, also known as Paraquat, chemically named 1.1'-dimethyl-4.4'-dichlorodipyridine cation salt, is an organic heterocyclic contact defoliant and herbicide. Paraquat has been used as a quick-acting defoliant since 1962. Natural contact herbicides are widely used. The original drug is a white or yellow solid, easily soluble in water and widely used in agricultural weeding. It has become the most widely used herbicide in the world. However, during the use of herbicides, the environmental water and soil were polluted, and it was found that it had a greater impact on human health. After the human body accidentally ingests or directly contacts with paraquat, it can be absorbed throu...
