1. the invention provides that a kind of operating procedure is simple, absorption Ag+Ability is strong, adsorbance and the high naval stores of clearance and preparation method thereof, and its method and step are as follows:

  • Carboxymethyl potato starch is mixed with a certain amount of deionized water;

    Weighing a certain amount of acrylamide, it is reacted with the acrylamide weighed up by preparation sodium hydroxide solution by certain degree of hydrolysis;

    Above-mentioned carboxymethyl potato starch is mixed homogeneously with the acrylamide solution of sodium hydroxide partial hydrolysis with the mixed liquor of deionized water in reaction bulb, add a certain amount of initiator potassium persulfate and a certain amount of cross-linking agent N, N '

    -methylene-bisacrylamide, stirring is allowed to uniform, it is passed through nitrogen, it is slowly heated, temperature of reaction system is made to be stepped up, polyreaction occurs between 30-60 DEG C, temperature continues rising and reaches insulation 1.5h when 80 DEG C, then take out product, drying, pulverize and i.e. obtain absorption Ag+Resin;

    It is the solution of 10mg/ml, cross-linking agent N that the initiator potassium persulfate of above-mentioned use is configured to concentration, and N '

    -methylene-bisacrylamide is configured to the solution that concentration is 2.5mg/ml.
