This document specifies a rapid colloidal gold immunochromatographic detection method for diconitrile residues in vegetables and fruits. This document is suitable for the rapid detection of dicofenil residues in vegetables and fruits. Note 1: Vegetables include kale, cucumber, zucchini, ginger, cabbage, eggplant, kidney beans, and Chinese cabbage. Note 2: Fruits include dragon fruit, tangerines, tangerines, oranges, apples, pears, mulberries, and kiwis. This method adopts the principle of competitive inhibition immunochromatography. After extraction, the fenfonitrile in the sample combines with the colloidal gold-labeled specific antibody, inhibiting the binding of the antibody to the antigen on the test line (T line) in the test strip, resulting in a change in the color depth of the test line (T line). . By comparing the color depth of the test line (T line) and the quality control line (C line), a qualitative analysis of the pyrochloride in the sample was performed.
