Malgorzata Grabarczyk and Anna Koper from Maria Curie-Sklodowska University, Poland, report a simple and sensitive stripping voltammertric method to determine trace amounts of uranium in natural water samples in this communication. They used an Amberlite XAD-7 or XAD-16 resin to eliminate interference from the surfactants that are often present in environmental samples.
The procedure is based on the adsorptive accumulation of the U(VI)–cupferron complex onto a hanging mercury drop electrode, followed by a reduction of the adsorbed species by a voltammetric scan using differential pulse modulation.
The paper will be free until 13th May.
