Abstract

The major-element matching method was used to eliminate matrix interference.Experimental conditions including acid degree and reducing agent concentration were optimized,Good linear relations with fluorescence strength were obtained for As,Sb,Bi in the concentration ranging from 1 to 200μg·L-1.Recovery rates from 92% to 101% were achieved with relative standard deviation ranging from 2.7% to 5.5%.
