mineral acids and Iron(III) extraction
 
Description Fe(III) was extracted from mineral acids (HCl, HNO3, and H2SO4) into paraffin containing TBP and n-decanol (solvating agent for Fe(III)-TBP complex), using a bulk liquid membrane extractor. Both the extraction equilibria and kinetics of extraction were determined. Rate of extraction of Fe(III) by TBP was found to depend on the acid in the order HCl>HNO3 >> H2SO4. TBP was found to co-extract acid with the rate in order HNO3> H2SO4>HCl. The rate of coextraction of acid was significantly enhanced in the presence of Fe(III). A kinetic model to predict concentration of mineral acid and Fe(III) during extraction was developed and validated.
