摘　　要：探讨了使用微波灰化技术消化原油和成品油样品,并使用氢化物发生-原子荧光光谱法测定其中铅和砷的含量。研究了铅测定的灰化保护剂和砷测定的灰化助剂,并优化了仪器工作条件和实验条件。该方法测定原油和重油中铅的平均回收率分别为96.8%和96.7%,相对标准偏差分别为1.03%和0.93%;测定原油和重油中砷的平均回收率分别为90.0%和90.3%,相对标准偏差分别为2.39%和2.63%。A determination method of lead and arsenic in crude oil and fuel oil by hydride generation atomic fluorescence spectrometry,using microwave ashing as samples pre-treatment means was established. The ashing protector for Pb and ahing assistant for As were studied. Meanwhile,the operative conditions of hydride generation atomic fluorescence spectrometry were optimized. The average recoveries were 96.8% and 96.7%,and the RSD were 1.03% and 0.93% for determination results of Pb in crude oil and fuel oil. The av...
