Abstract

As,Sb and Bi in copper concentrates were determined by hydride generation atomic fluorescence spectrometry.The major element matching method was used to eliminate matrix interference.Experimental conditions including acid degree and reducing agent concentration were optimized.Good linearilities were obtained for As,Sb,Bi in the concentration range of 1—200μg·L~(-1).Recoveries from 92% to 101% were obtained with relative standard deviation of 2.7%—5.5%.
