A selective, sensitive and reliable ion chromatographic method was developed for the direct simultaneous determination of cyanate, thiocyanate and Cr(VI) with conductivity dedection. Since cyanides can not be dedected in these method, free cyanide ions were converted into cyanate with chloramine-T at alkaline pH. Proposed methods were applied for the simultaneous determination of cyanide and chromium(VI) in electroplating bath solutions and in industrial wastewater. Cyanide and chromium(VI) could be measured in the linear dynamic ranges of 0.6 – 961.5 μmol L‾1 and of 0.9 – 118.5 μmol L‾1, respectively. The limit of detection and limit of quantification of cyanide were 0.18 and 0.61 μmol L‾1, and these values for chromium(VI) were 0.26 and 0.86 μmol L‾1, respectively.
