摘要
在线双管氢化AAS法是一种新的原子吸收氢化光谱法 ,具有简便、快速、灵敏度高和硼氢化钾用量少的优点。采用正交试验设计法对在线双管氢化AAS法测定低含量As、Sb和Bi的测定条件进行了系统的研究 ,确定了乙炔流量、燃烧器高度、硼氢化钾浓度和溶液酸度的最佳测定条件。在最佳条件下对实际样品土壤GSS -5、水系沉积物GSD -11、钨矿石GSO -W -1和GSO -W -2中As ,Sb ,Bi的含量进行了测定 ,测定的结果较准确 ,RSD <3 .2 6%。
By on-line double capillary atomic absorption spectrometry with hydride generation is a new sensitive and precise method. The conditions for determine As, Sb and Bi by on-line double capillary hydride generation\|atomic absorption spectrometry are investigated with orthogonal experiment design. The best measuring condition was determined by this way. The good results are oltained during the determination of samples, RSD<3.26%.
