摘要：

Copper(II) amine complexes supported on Amberlyst-15 cation resin were prepared and characterized by SEM, EDX and FTIR measurements. The kinetics of the heterogeneous oxidation of an organic dye, crystal violet, with H2O2 catalyzed by the supported catalysts was investigated in aqueous solution. The rate of reaction increases with increasing stability of the copper(II) amine complexes. The oxidation rate attained a first-order in the catalyst and the dye only at lower concentrations and second order in H2O2. A very fast formation of a peroxo-dye intermediate resulting from the interaction of H2O2 with the dye even in the presence of the catalyst was observed. (C) 2001 Elsevier Science Ltd.
