建立了果蔬中180种农药残留量的测定方法。该程序包括用乙腈提取，然后用无水硫酸镁和氯化钠盐析步骤。通过离心法同时进行沉淀物和水的去除。共萃取物用双层固相萃取柱去除，石墨化炭黑和伯仲胺(GCB/PSA)固相萃取净化柱。洗脱液用GC/FPD和牙胶测定，无需进一步净化。对9种基质的加标回收率为0.05~0.1mU/g，180种农药的加标回收率主要在70~110%，相对标准偏差(RSD)在25%以下。被测农药的检出限在0.01~0.05微克/克之间。(C)日本农药科学学会。
A method was established for the determination of 180 pesticide residues in fruits and vegetables. The procedure involved extraction with acetonitrile, followed by a salting-out step with anhydrous MgSO4 and NaCl. Removal of sediment and water was performed simultaneously by centrifugation. Co-extractives were removed with a double-layered SPE column, and graphitized carbon black and primary secondary amine (GCB/PSA) solid phase extraction cleanup cartridge. The eluate was determined by GC/FPD and GUMS without further cleanup. Recovery data were obtained by fortifying 9 matrices at 0.05-0.1 mu g/g. Recoveries of 180 pesticides were mainly 70-110% and the relative standard deviation (RSD) was below 25%. Limits of detection ranged between 0.01 and 0.05 mu g/g for tested pesticides.
