摘要
建立25%氟吗啉·唑菌酯悬浮剂在人参土壤上残留分析方法。样品经过乙腈提取,弗罗里硅土层析柱净化,高效液相色谱法进行定量分析。此条件下氟吗啉和唑菌酯的平均回收率分别是87.9%~99.0%和89.2%~99.9%,相对标准偏差为2.7%~7.3%和1.9%~13.4%。氟吗啉在人参土壤中的降解半衰期为2.7~10.7d,唑菌酯的半衰期为0.3~18.4d。该方法简单,快速,适用于人参土壤中氟吗啉和唑菌酯的残留分析。
The aim was to establish a residue analysis method of flumorph and pyraoxystrobin 25%sc in ginseng soil sample.The samples were extracted with acetone,cleaned-up with florisil and analyzed by HPLC.The recoveries offlumorph andpyraoxystrobin were 87.9%~99.0%and 89.2%~99.9%with relative standard deviation of 2.7%~7.3%and 1.9%~13.4%respectively.In ginseng soil samplethe half-life of flumorph was 2.7~10.7d and the half-life of pyraoxystrobin was 0.3~18.4d.This method is simple,rapid and sensitive,andcan be used to determine flumorph andpyraoxystrobin residue inginseng soil sample.
