  • METHOD FOR RAPIDLY DETECTING PESTICIDE BASED ON THIN-LAYER CHROMATOGRAPHY AND ENZYME INHIBITION PRINCIPLE
    Publication number: 20240110900
    Abstract: A method for rapidly detecting pesticides based on thin-layer chromatography (TLC) and enzyme inhibition principles. The method includes the following steps: cutting a TLC plate into a rectangle, and using one end of the rectangle to contact a sample extract to form a pesticide residue separation area; covering the other end of the rectangle with a small piece cut from filter paper or glass fiber and fixing on a piece of enzyme inhibition reaction test paper to form a pesticide enrichment area; pasting a side of the enzyme inhibition reaction test paper away from the pesticide residue separation area with a piece of filter paper immobilized with a chromogenic agent to form a substrate color development area; and performing color reaction.
