摘要：

The anions H2PO2 -, H2PO3 - and H2PO4 - along with Cl-, NO3 - and SO4 2- have been simultaneously determined by single-column ion chromatography in an Indirect ultraviolet detection mode. The analytical approach employs 4-amino-2-hydroxybenzoic acid as an eluent at 4mM in the pH range 5.5-6.5 and at a 2ml/min flow rate. Clean separations occur on a polymeric analytical column within 10min, and the anions can be quantified in the sub-ppm range. © 1990, The Japan Society for Analytical Chemistry. All rights reserved.
