  • Patent number: 6989102
    Abstract: An alginate gel adsorbent to remove heavy metal ions according to the present invention is prepared by adding dropwisely 0.1-5 wt % alginate solution to a polyvalent cationic solution thereby cross-linking alginic acid with polyvalent cations. An alginate gel adsorbent containing activated carbon capable of simultaneously removing heavy metal ions and organotoxic materials, that is, activated carbon/alginate gel adsorbent, is prepared by adding dropwisely a mixed solution of 0.17-10 wt % of alginate and 0.1-10 wt % of activated carbon powder to a polyvalent cationic solution thereby cross-linking alginic acid with polyvalent cations in order to immobilize polyvalent cation to alginic acid containing activated carbon. The polyvalent cationic solution is selected from the group consisting of calcium chloride (CaCl2), strontium chloride (SrCl2), barium chloride (BaCl2) and aluminium chloride (AlCl3).
