| 摘 要： | 目的]建立了敌稗在稻田环境中的残留检测方法.方法]样品经乙腈提取,液液分配后,气相色谱-电子捕获(ECD)法测定.结果]方法对敌稗在田水、土壤、植株、稻米和稻壳中的平均添加回收率为84.6％～105.5％,相对标准偏差1.0％～12.5％.敌稗在水稻田水、土壤、植株中的半衰期分别为0.9～2.9、0.7～2.0、1.0～1.3 d；在收获期土壤、植株、稻米、稻壳中敌稗的残留量均小于最低检测质量浓度.结论]该方法操作简单、快速,灵敏度高,符合农药残留分析的技术要求.

| Abstract: | The aim was to establish a method for the determination of propanil in rice field environment.Methods] Propanil were extracted from samples with acetonitrile and determined with GC-ECD after liquid-liquid partition.Results] The results indicated that the average recoveries of propanil spiked in water,soil,straw,rice,and bran samples ranged from 84.6-105.5%.And the relative standard deviation was 1.0-12.5%.The half-lives of degradation of propanil was 0.9-2.9 d in paddy water,0.7-2.0 d in paddy soil and 1.... |
