摘    要:建立了氢化物发生-原子荧光光谱法测定精锑中砷的方法。试料用王水溶解,通过加入酒石酸抑制基体锑的水解,用硫脲-抗坏血酸将As(V)还原成As(Ⅲ),从而不需通过化学分离,直接测定精锑中的砷。方法的检出限为0.210ng/mL,相对标准偏差(n=11)为2.58%。

关 键 词:精锑    氢化物发生-原予荧光光谱

Abstract:A method for analyzing arsenic in fine antimony by hydride generation atomic fluorescence spectrometry was established. The sample was dissolved with aqua regia. Arsenic was determinated without chemical seperation in the medium by adding tartaric acid to inhibit the hydrolysis of antimony, adding thiourea-ascorbic acid to restore As(Ⅴ)to As(Ⅲ). The detection limit was 0.210 ng/mL for As. The relative standard deviation(RSD, n = 11)was 2.58%.
Keywords:fine antimony  arsenic  hydride generation atomic fluorescence spectrometry
