摘要:

阐述了新型聚合物重金属离子吸附剂的合成与改性及其对水溶液中Cd(Ⅱ)、Pb(Ⅱ)、Cu(Ⅱ)、Hg(Ⅱ)等重金属离子的吸附性能。这些聚合物重金属离子吸附剂对低浓度的重金属离子表现出了较好的吸附能力,其中聚合物吸附剂PGHyFeO-COOH对mg/L级的Pb(Ⅱ)、Cd(Ⅱ)、Hg(Ⅱ)的最大吸附量分别为211.4mg/g、155.0mg/g、147.2mg/g。这些吸附剂的吸附速度也较快,平衡吸附时间一般在60min左右,有的甚至只有几分钟。新型聚合物重金属离子吸附剂在水处理工业中具有广阔的应用前景。

Abstract:

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.

Key words: polymer sorbent, heavy metals ions, adsorption performance
