Abstract


This paper reports the studies on the solvent extraction behavior of Cr (VI) in different acid solutions using tetrabutyl ammonium iodide in benzene as extractant. The effect of important variables like nature of diluents, concentration of mineral acids, and variation of metal ion concentration and extractant variation is investigated. The extractions are nearly quantitative with hydrochloric, sulphuric, nitric and perchloric acid & are partial from phosphoric and acetic acid systems. The extracted species are identified. The method has been applied for the determination of chromium in chrome alloys.
