A sensitive procedure has been developed for the kinetic-photometric determination of copper(II) in natural non-saline and saline waters by flow-injection analysis. The procedure is based on hydroquinone oxidation by hydrogen peroxide in the presence of copper(II) trace concentrations. An alternative scheme of copper(II) determination has been proposed, which provides the elimination of the high background signal associated with non-catalytic reactions. The procedure based on the alterative scheme has lower detection limit of 0.16 μg/L and a wide analytical range of 0.5-20 μg/L copper. The characteristics of catalytic reaction rates in two procedures are compared. The duration of single analysis does not exceed 6 min. © 2013 Pleiades Publishing, Ltd. Source

A procedure is developed for flow-injection potentiometric determination of trace chloride ions in low-mineralized waters and atmospheric precipitations. The procedure excludes the stage of preliminary ion-exchange concentration. The quantification limit in a 5-min analysis is 0.4 mg/L. © 2010 Pleiades Publishing, Ltd. Source
