摘要：

The separation and quantitation of phosphorous oxoanions have been investigated by non-suppressed ion chromatography (IC) with conductometric detection using a modified gluconate-borate buffer as eluent. Hypophosphite being coeluted with the injection peak, its previous oxidation into phosphate is necessary. The method was applied to the determination of hypophosphite and phosphate in several pharmaceuticals.
