Title: Cationic red-violet - a selective reagent for the extraction-photometric determination of lead

To increase the selectivity of the determination of lead, the authors investigate the complex formation of lead with bromide ions and the basic cyanine dye, cationic red-violet (CRV). In contrast to the triphenylmethane, rhodamine, azine, thiazine, and azo-dyes, CRV forms ionic associates with bromide complexes of lead, which are extractable by inert solvents. This permitted the authors to develop a new, highly selective method of extraction-photometric determination of lead.
