| Abstract: | The extraction equilibrium between aqueous iron (III) sulphate solutions and amine Primene 81R was studied. The results show that the free amine extracts iron(III) from these solutions. The extracted complex has been isolated and can be represented by the stoichiometric formula 4RNH2·Fe2(SO4)3. The extraction reaction is almost independent of temperature and change in the diluent of the organic phase. On the basis spectral studies a structure for the extracted complex is suggested. |
