摘　　要：研究了酒石酸介质中氢化物发生原子荧光光谱法 ( HG- AFS)测定多金属矿中痕量锡的方法 ,考察了不同酸介质和浓度对氢化物发生效率的影响 ,试验了共存元素的干扰情况。方法的检出限为 1 .4× 1 0 - 10 g/ m L,精密度 ( n=5)为3.71 %～ 5.38%。A method for determination of trace Sn by hydride generation atomic fluorescence spectrometry (HG AFS) was described. The influence of HG AFS operation conditions,various acidic media and concentration of NaBH 4 solution was studied.The detection limit is 1.4×10 -10 g/mL. The method was applied to determination of trace Sn in the standard multimetal ore samples. The results were in good agreement with certifid values with precision of 3.7%～5 4% RSD( n =5).
