Capillary electrophoresis is used as a screening protocol for the dete
rmination of uranyl ion complexed with Arsenate III. Long sample plugs
are injected and stacked to narrow zones. Capillary column inner diam
eter, 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.
