Abstract

The extraction of chromium (III) from hydrochloric, sulphuric, nitric and perchloric acid solutions with Tributylphosphine Oxide (TBPO) in chloroform has been studied. The extractions from nitric, hydrochloric and sulphuric acid solutions are nearly quantitative and are partial from perchloric acid solutions. The optimum conditions were evaluated by varying the experimental conditions such as pH, shaking period, concentration of metal ion, Tributylphosphine oxide, anion and various diluents on the extraction. The extracted species are identified.

Keywords: Chromium (III), Tributylphosphine Oxide (TBPO), extraction, chloroform
