Determination of Cobalt in Water by FAAS

Wei En

Abstract

The cobalt in water was determined directly by FAAS,and the working conditions of the instrument were studied and optimized.The detection limit(3s/k) of the method was 0.005mg/L. The proposed method was applied to the analysis of standard samples(03603),and the values were accurate,the standard deviation was 1.3mg/L with RSD of 1.6%,all of these meet the quality control standard of laboratory.
