چکیده انگلیسی
A macro matrix solid-phase dispersion (MSPD) method was developed to extract 266 pesticides from apple juice samples prior to gas chromatography-mass selective detection (GC-MSD) determination. A 10Â g samples was mixed with 20Â g diatomaceous earth. The mixture was transferred into a glass column. Pesticide residues were leached with a 160Â mL hexane-dichloromethane (1:1) at 5Â mL/min. Two hundred and sixty-six pesticides were divided into three groups and detected by GC-MSD under selective ion monitoring. The proposed method takes advantage of both liquid-liquid extraction and conventional MSPD methods. Application was illustrated by the analysis of 236 apple juice samples produced in Shaanxi province China mainland this year.
