摘要：

Post-column, on-line photolytic derivatization in liquid chromatography with electrochemical detection for some inorganic anions is described. Flow injection analysis and ion-pair reversed-phase chromatography followed by photolysis and electrochemical detection were used for the determinations of anions. Several operation conditions, such as mobile phase, lamp used for the photolysis, flow-rate, and applied potential, have been optimized for the determinations. Analytical figures of merit were determined. Method validation was carried out by the analysis of single blind, spiked samples. Inherent from the advantages of electrochemical detection in liquid chromatography, the methods is of high sensitivity and selectivity for anion analysis. © 1990.
