CHELATE RESIN FOR ADSORBING SPECIFIC HEAVY METAL ION |
摘要 |
PURPOSE: A chelate resin for adsorbing specific heavy metal ions and its preparation method are provided, to improve the adsorbing property to specific heavy metal ions by introducing a sulfonyl dithiocarbamic acid group into the phenyl ring of a spherical polystyrene as a chelate functional group and thereby improving the hydrophilicity and the coordinating property. CONSTITUTION: The chelate resin is represented by the formula 1, wherein A is H, K or Na. The method comprises the steps of preparing a spherical polystyrene by suspension polymerization of styrene using a divinylbenzene as a crosslinking agent, and reacting the spherical polystyrene with chlorosulfonic acid to obtain the chlorosulfonated copolymer represented by the formula 2; aminating the copolymer of the formula 2 by using liquid ammonia to prepare the sulfonamide group-containing copolymer represented by the formula 3; and reacting the copolymer of the formula 3 with carbon disulfide to introduce a dithiocarboxylic group into the copolymer and neutralizing the obtained one.
