Rapid Speciation of Inorganic Se(IV) and Se(VI) Compounds by Flow Injection-Capillary Electrophoresis System with Contactless Conductometric Detection and Hydrostatic Pressure Generated Flow.

Original language description

Flow injection -- capillary electrophoresis system with contactless conductivity detection and hydrostatic pressure generated flow was used for fast and sensitive speciation of Se(IV) and Se(VI) and simultaneous determination of other common inorganic anions. The sample throughput was 25 samples per hour using the background electrolyte solution containing 8.75 mM L-histidine adjusted to pH 4.00 with acetic acid. The repeatability of peak areas (n = 8) was better than 1.41% and The limits of detection were 190 mgL-1 and 7.5 mgL-1 for Se(IV) and Se(VI), respectively. The interference from carbonate, typically present in water samples, was eliminated by using a low pH electrolyte in which carbonate is uncharged and migrates at the EOF front. The method was applied to the analysis of Se(IV) and Se(VI) in soil samples that were spiked with both selenium species and the results for recovery of both selenium species were in good agreement with their introduced concentrations. The method is s
