Abstract
A highly sensitive and selective ion-chromatographic procedure with UV detection at 227 nm was developed for the determination of trace amou nts of iodide. The procedure utilizes 0.1M NaOH as eluent, which enabl es the determination of 1-100 mu g l(-1) I- with a precision of ca. 6% . 1000-fold amounts of other anions such as fluoride, chloride, phosph ate, sulphate, bromide, nitrite and nitrate do not interfere. The meth od has been applied to determine iodide in sea water samples from the Indian coast.
