Abstract

The method of pretreatment to determine trace amounts of Br ,NO 3 and SO 4 2 in sea water by ion chromatography was proposed, by which the electrolysing argentine electrode was used to minimize the disturbance of Cl -. The results indicate that the method is simple, convenient, quick and efficient with recovery rates over 95 percent.
