Comparasion of Three Detection Dethods for Paraquat Residues in Food

Abstract:

This study investigated the detection methods and the corresponding detection parameters of paraquat(PQ).A serials of results were achieved:(1)The minimum limition of HPLC was 12 mg/L,the recovery ration was 42～52%,the RSD was 4.43%,the precision was very high.(2) the parameters of ELISA were:minimum limitation 0.005μg /L,the recovery ratio 70～80%,RSD 8.15%;.(3)The detection results of GICA is very good,minimum limition 50 mg/L,through a standard color reflected series.Among these detection protocols,GICA method has been proven to be a simple,efficient,quick method to determine the content of PQ in food.
