The synthesis and chemical modification of novel polymer sorbents for heavy metal ions, such as Cd(Ⅱ),Pb(Ⅱ),Cu(Ⅱ),Hg(Ⅱ) in aqueous solutions, are discussed. These polymer sorbents perform higher capacity to remove heavy metal with low concentration, like mg/L, even μg/L. For example, the maximum adsorption capacities of Pb(Ⅱ), Cd(Ⅱ), Hg(Ⅱ) by PGHyFeO-COOH are 211.4 mg/g, 155.0 mg/g, 147.2 mg/g, respectively. The adsorption rate is fast and the equilibrium adsorption time is about 60 min, or sometimes is even several minutes. The polymer for adsorption of heavy metal ions will be the novel sorbents with great potential development in water treatment industry.
