CATALASE-LIKE ACTIVITY OF DIVINYLBENZENE (DVB)-CROSS-LINKED POLYACRYLAMIDE-SUPPORTED AMINO METAL-COMPLEXES

The catalytic properties of the complexes resulting from the interacti on between a DVB-crosslinked polyacrylamide supported amine and Cu(II) , Cr(III), Fe(III), Mn(II) and Pb(II) ions have been investigated. The study of hydrogen peroxide decomposition was employed as a model reac tion for this purpose. The phenomenological aspects of this process su ch as time-course, dependence of H2O2 concentration, complex concentra tion, temperature and pH were evaluated. The activation energy of deco mposition was calculated to be 16.35 kJ/mol. The results indicate a ca talase-like activity for these metal complexes. Copyright (C) 1996 Els evier Science Ltd
