The solvent extraction of neutral red chlorothallate(III) from aqueous HCl solutions was studied. The compound formed is readily extracted with amyl acetate. The optimum conditions for the formation and extraction of the ion pair were found. The ratio of the reacting components in the compound formed was determined. The extraction selectivity in the presence of several interfering elements was studied. A procedure for the solvent extraction–fluorimetric determination of trace thallium(III) was developed. The procedure was used for the analysis of manganese oxide ores.
