| Abstract: | [Aims] This study aims to establish a colloidal gold immunochromatographic method for the rapid detection of dicofol residues in fruits. [Methods] On the basis of the optimization of solid-phase carrier, a colloidal gold immunochromatography method was established based on the competitive inhibition model. [Results] The results showed that the detection limit of dicofol in fruits was 1.0 mg/kg, which met the requirements of the national standard for the maximum residue limit of dicofol in fruits, and the specificity was good. [Conclusions] This method is fast,simple, economic and suitable for the field screening and detection of dicofol residues in fruits. |
