(cest2017_01101) Transport through a membrane of Fe(II) and Fe(III) from chloride medium using tri-n-butylphosphate and tri-noctylamine as carrier

摘要

The aim of this work is to investigate extractionof divalent iron and trivalent iron from chlorides solutionsby Tri-n-butyl phosphate(TBP) and Tri-n-octylamine(TOA) dissolved in kerosene.The physical and chemicalparameters have allowed us to obtain the variables givingthe optimum extraction efficiency.A chemicalmodelization has allowed us to suggest the extractionmechanism. The classical behaviour obtained insurroundings has been found, with an anion exchangermechanism and solvation mechanism.
