The first observation of the catalytic wave of BrO3 - at a dropping mercury electrode at the potential of the reduction of Cr(III) to Cr(II) in an ammonium buffer solution is reported. A mechanism is proposed for the ...

It is shown that the analytical signal in a flow-injection system with voltammetric detection can, in principle, be measured by the catalytic current of hydrogen liberation in solutions of nickel(II) cysteinates in the ...

The oxidation of hydroxylamine by hexacyanoferrate(III) is proposed as an indicator reaction for kinetic determining copper(II) traces (detection limit of 2 × 10-8 M). It is shown that iron(II) and total iron can be ...

A procedure for the selective determination of Phosalone and Carbophos in their alkaline hydrolyzates using a carbon-paste electrode modified with cobalt(II) 2,2′-dipyridylate was developed. The preconcentration of pesticides ...
