Ion chromatography, coupled with electrochemical detection, was applied in determining cyanide concentrations in the waste waters generated by the processing of calthode electrodes in the aluminum industry. Ion chromatography data were compared with the results obtained from conventional spectrophotometric techniques. The ion chromatography data were found to be statistically bias high.
