Determination of chromium from a hydroxylamine catalytic current by flow-injection analysis

Abstract

A catalytic wave was first found on a dropping mercury electrode in the system Cr(III)-hydroxylamine-ammonium buffer solution studied by conventional polarography and flow-injection analysis. This catalytic wave can be used for the flow-injection determination of low concentrations of Cr(III). © 1998 MAEe cyrillic signK Hayκa/Interperiodica Publishing.
