摘要：

The catalytic decomposition of hydrogen peroxide was studied kinetically in presence of the resin Dowex-50w in the form of mono (mea)-di (dea) -and tri(tea) - ethanolamine- Ni (II) complexes in an aqueous medium. The rate constant, k (per g of dry resin) was estimated over the temperature range 25-40-degrees-C. The reaction was first order with respect to [H2O2] in all cases. The value of the rate constant increased in the following sequence : tea < dea < mea, which is the same sequence of the basic strength of the free amines. The activation parameters were calculated. Probable mechanism for the reaction was proposed.
