Abstract:
Objective A method was developed for the determination of cyanide in water by ion chromatography with direct amperometric detection.Methods The eluent used was 0.1 mol/L NaOH and 10%(V/V) acetone.The samples were analyzed by using ion chromatography as well as external standard curve.The effects of 7 common ions,2 electrochemical active substances on the determination of cyanide were studied.Results The linear range of the method was 0.05-100 ?g/L and the correlation coefficient was 0.999 1.The RSD was
