An HPLC method using an external standard was developed for quantitative determination of the pirimicarb residues in wheat seed. 采用甲醇超声波提取和液液分配技术净化提取物,反相高效液相色谱测定,建立了检测小麦籽粒中抗蚜威残留量的方法。
Pirimicarb in vegetables and fruits was determined with PSA dispersive solid-phase extraction cleanup and HPLC fluorescence detection. 以PSA分散固相萃取净化,液相色谱柱分离,直接荧光法测定灭定威,研究建立了测定蔬菜、水果中灭定威的分析方法。
As time went on,the residual weight of pirimicarb in different organs of the cucumber decreased,which was in keeping with the first-order kinetic equation. 抗蚜威在黄瓜不同器官中的残留量随着时间延长而递减;符合一级反应动力学方程.
The MSPD-HPLC technigue used for assay of trace pirimicarb and amitraz in fruit and vegetable was discussed and the conditions of quantitative analysis investigated in detail. 试验将MSPD技术用于水果、蔬菜中抗蚜威和双甲脒残留物的高效液色谱分析,并对定量检测条件作了详细的研究。
the selectivity of pirimicarb was secondary high; 其次是抗蚜威对天敌和绣线菊蚜的选择性较高；
