摘要：

TiO2, Fe2O3 and Fe3+ have been immobilized on low cost polyethylene films containing anhydride anchoring groups showed enhanced mineralisation rates for chlorophenols and Orange II, compared to previously reported immobilized catalysts with rates which are comparable to or greater than catalytic suspensions.
