UPLC-MS/MS法同时检测葡萄和土壤中2种甲氧基丙烯酸酯类杀菌剂残留
Chinese Journal of Analysis Laboratory（2020）
Abstract
采用改进的QuEChERS方法,结合UPLC-MS/MS,建立了葡萄和土壤中同时测定嘧菌酯和吡唑醚菌酯残留快速分析方法.葡萄样品采用乙腈提取,无水MgSO4+乙二胺-N-丙基硅烷+C18固相分散剂净化,土壤样品采用乙腈提取,无水MgSO4+ C18固相分散剂净化,UPLC BEH C18色谱柱分离,三重四极杆电喷雾质谱检测.在质量浓度0.01 ～ 5.0 mg/L范围内,葡萄和土壤基质中两种杀菌剂的浓度与峰面积之间具有良好的相关性,相关系数均大于0.99;在葡萄和土壤中添加0.1～5.0 mg/kg的嘧菌酯与吡唑醚菌酯,回收率为88.1％ ～ 109.2％,相对标准偏差为1.4％ ～ 6.4％.该方法适用于葡萄中和土壤中同时快速检测嘧菌酯和吡唑醚菌酯残留.
