Catalase-like Catalytic Activity of Ion-Exchange Resins Modified with Metalloporphyrins

抄録

In an attempt to develop good artificial mimesis of catalase, the catalase-like catalytic activity of common ion-exchange resins modified with various metalloporphyrins was estimated in terms of their activity to accelerate in the decomposition of hydrogen peroxide. The anion exchange-resin modified with manganese-tetrakis(sulfophenyl)porphine was found to be the best. This resin retained its activity after repeated use (ten times). The presence of manganese or cobalt as a central metal ion was found to be essential for the activity.
