| 摘 要： | 合成了含双亚砜及3-氨基吡啶的新型螯合树脂,并进行了红外光谱、比表面积、孔径和元素分析表征。研究了不同pH下该树脂对Mn2 、Cd2 、Pb2 、Cu2 、Zn2 、Hg2 等金属离子的静态饱和吸附量以及在pH=6时该树脂对Hg2 的动力学吸附和热力学吸附。实验结果表明,该树脂对Hg2 的吸附量最大,达到0.82mmol/g,对Hg2 吸附属于液膜扩散控制。等温吸附研究表明,该树脂对Hg2 的吸附可用Langmuir方程描述。

| Abstract: | A new chelating resin containing bis(sulfoxide and 3-aminopyridine) was synthesized. Its structure was characterized by IR spectra, surface area, pore size and elemental analysis. The adsorption capacities of the resin for Ni2 , Cd2 , Pb2 , Cu2 , Zn2 , Hg2 were investigated at pH=2 and 6. The adsorption kinetics and adsorption thermodynamics of the resin for Hg2 were also studied. The experimental results showed that: the resin had high affinity for Hg2 . The maximum capacity at pH=6 was 0.82mmol/g. The adsorption was controlled by liquid film diffusion. The adsorption mechanism of the resin for Hg2 could be depicted by Langmuir equation. |
