ABSTRACT:
Metal complexes of 8-hydroxyquinoline and polymeric water-insoluble but water-swellable cross-linked N-vinyllactam or N-alkyl-N-vinylamide polymers in the form of porous beads or granules and a process for preparing same. Such complexes are particularly suited for use as algicides, fungicides, slimicides, and bacteriocides in the treatment of water such as in gravity filtration systems, canisters or packed columns having the advantage of rapid throughput. The complexes may be prepared by adsorbing the hydroxyquinoline onto the cross-linked N-vinyllactam or N-alkyl-N-vinylamide in the form of porous beads or porous granules and subsequently forming the metallic complex in solution.
