摘要
本文研究了在王水分解样品后的同一份溶液中采用氢化物原子荧光光谱法连续测定砷、锑、铋、汞的方法。在拟定的测定条件下 ,线性范围宽 ,标样分析结果与推荐值吻合。各元素的检出限分别为 As 0 .5ng/m L、Sb 0 .1ng/m L、Bi 0 .2 ng/m L、Hg 0 .0 8ng/m L。经近十万多件化探样品的测定 ,效果良好。
Rapid determination of As,Sb,Bi,Hg in geochemical sample by HG AFS was researched.The effects of operation condition were studied and the instrument parameters were optimized.The detection limits for As,Sb,Bi,Hg is 0.5ng/mL,0.1ng/mL,0.2 ng/mL,0.08 ng/mL respectively.The method is simple and rapid with high sensitivity.It has been applied to the determination of 100000 samples with satisfactory results.
