Abstract
An ion chromatographic method using an ion-exchange column for the simultaneous analysis of sulphate and chlorate in industrial salt and sodium chloride brines has been developed. A mixed eluent of 2.0 m M sodium carbonate and 0.75 m M sodium bicarbonate is used. The effects of various parameters have been reported and critically discussed. The results are precise and afford simultaneous determinations of sulphate and chlorate.
