Reduction of Thiocyanate Complexes of Fe(III) in the Presence of Activated Carbon
Fe (III) complexed with SCN- was found to be reduced to Fe(II) in the presence of activated carbon. The rate of disappearance of the complex was determined spectro photometrically and was found to be first order with respect to Fe(I1I). The enthalpy and entropy of activation are 100 ± 10 kJ/mole...

| Summary: | Fe (III) complexed with SCN- was found to be reduced to Fe(II) in the
presence of activated carbon. The rate of disappearance of the complex was
determined spectro photometrically and was found to be first order with respect
to Fe(I1I). The enthalpy and entropy of activation are 100 ± 10 kJ/mole and
14.1 ± 0.8 J/mole-K respectively. Some Fe was found to be adsorbed on the
catalyst where the actual reduction was suggested to take place. The accompanying
oxidation reaction has been suggested to be mainly that of the thiocyanate
ions adsorbed at the positive centres on the catalyst. |
