“…Most of these are expensive, time consuming and instrumentally complicated. Simpler methods have been effective which depend on spectrophotometry and require the use of masking agents or a separation such as HPLC, ion chromatography or extraction; however, most of these methods use large volumes and are slow (5,(9)(10)(11)(12)(13)(14)(15).…”

Journal of Liquid ChromatographyPublication details, including instructions for authors and subscription information:ABSTRACT Capillary electrophoresis is used as a screening protocol for the determination of uranyl ion complexed with Arsenazo Ill. Long sample plugs are injected and stacked to narrow zones. Capillary column inner diameter, running buffer constituents and concentrations, effective column length and injected sample plug length are optimized and discussed. A limit of detection of 10 ppb is achieved with a linear dynamic range of nearly 3 orders of magnitude in concentration injected. Analytical figures of merit are presented and river water samples are analyzed. 3699
