摘要
Abstract
Using 12 blank fruit matrices as solvents,15 organic phosphorus pesticides were prepared into mixed standard solutions of 0.05,0.10,0.20,0.40 and 0.80 mg/L,and compared with acetone solvent.The matrix effect of organic phosphorus pesticide residues in different fruit matrices was determined by gas chromatography.The results showed that 15 organic phosphorus pesticides exhibited varying degrees of matrix effects in 12 fruit substrates,with most pesticides exhibiting matrix enhancement effects,and there was no necessary correlation between pesticides and concentrations.Therefore,when conducting the detection of organic phosphorus pesticide residues in fruits,it is recommended to use a matrix instead of acetone as the solvent for standard preparation,which can greatly reduce the interference of the matrix on the detection results and improve the accuracy of the detection results.关键词
