高盐雾化器氢化发生新技术及电感耦合等离子体原子发射光谱同时测定沉积物中As、Sb、Se等氢化发生元素

Simultaneous Determination of As,Sb,Se in Sediment Samples with Hydride Generation Technique Using High Salt Nebulizer Combined with ICP-AES

用高盐雾化器（ＢａｂｉｎｇｔｏｎＮｅｂｕｌｉｚｅｒ）作为氢化发生装置与电感耦合等离子体原子发射光谱（ＩＣＰ／ＡＥＳ）结合同时测定氢化发生元素Ａｓ、Ｓｂ、Ｓｅ的分析方法，研究了在该氢化发生体系中共存过渡元素对以上元素的氢化发生的干扰及光谱干扰情况，评价了该法的检出限及多次测定的重现性，并用该装置测定了标准沉积物样品中Ａｓ、Ｓｂ、Ｓｅ的含量．

High salt nebulizer(Babington nebulizer)had been applied as a hydridegeneration device. The characteristics of the device was evaluated with the measurements ofAs,Sb,Se detectionm limits and the repeatabities for the mult-measurements. The detectionlimits of As,Sb,Se were 0.2,0.3 and 0.6 hg/ml,respctively. The interferences from thetransition metals on the hytlride generation of those elements were investigated.The systemdeveloped in the present work had been applied to the analysis of standard sediment samples.
