摘要
采用微波消解技术溶样，氢化物发生-原子荧光光谱法测定了出口芳香油中痕量铅。系统地研究了微波消解、氢化物发生的最佳条件，方法简便快速，在选定的实验条件下，方法检出限为0．25μg·L^-1，相对标准偏差小于5％，回收率为86．5％～100．5％。
Microwave digest technique in a closed vessel was used in decomposition of the essential oil for the subsequent determination of total Pb by HG-AFS. The experimental conditions of microwave digestion-hydride generation were optimized. The detection limit of the method was 0.25 μg· L^-1 and the RSD was less than 5%. The recoveries obtained were 86.5%-100.5%.
