Abstract:

Iron (III) has been extracted quantitatively from aqueous nitric and phosphoric acid solutions by benzene solutions of Tributyl phosphine oxide [TBPO] as extractant. Optimum conditions for extraction were established from the Study of the effect of several variables like– concentration of phosphine oxide, metal ion, acidity etc. The extracted species are identified. Stripping of iron (III) from the organic phase was also achieved with 1.0M NaOH. Extractions were nearly quantitative with both the acid solutions. Based on the results obtained, attempts were also made to estimate iron in industrial samples.

Keywords:

Extraction, iron (III), Tributyl phosphine oxide [TBPO], Industrial samples.
