Abstract

A method has been described for the extractive spectrophotometric determination of rhodium (III) with 2-thenoyltrifluoroacetone (TTA) in an acetone-xylene mixture. The bright yellow rhodium(III)-TTA chelate solution in an acetone-xylene solvent mixture obeys Beer’s law over the concentration range of 1.95–19.5 μg. of rhodium per ml. Around pH 6.0 quantitative extraction is possible with 0.015 M TTA -acetone-xylene. The colour of the complex is quite stable up to 72 hr. Rhodium(III) can be extracted in the presence of a large number of ions.
