Repetitive determination of copper(II) and regeneration of a chromogenic reagent using a cation-exchange column in a circulatory flow-injection system

The spectrophotometric determination of Cu(II) with 4-methyl-5-[(sulfomethyl)amino]-2-(2-thiazolylazo)benzoic acid(TAMSMB) was carried out by a cyclic flow-injection analysis. A cation -exchange column for on-line regeneration of the main reagent was incorporated in this FIA system, allowing a repet...
