摘要：通过在树脂上负载噻唑烷四磺酸酯制备了噻唑烷四磺酸酯改性树脂，用于吸附重金属离子。通过间歇吸附实验考察了不同树脂、树脂粒径、pH、接触时间、温度等因素对吸附性能的影响，并对吸附等温线、热力学、动力学、选择性和再生性能进行了研究。结果表明，D201树脂（大孔强碱性阴离子交换树脂）对噻唑烷四磺酸盐的负载能力明显高于D301树脂（大孔弱碱性苯乙烯阴离子交换树脂）和717树脂（强碱性苯乙烯阴离子交换树脂），并且随着D201树脂粒径的减小而增大。对重金属离子的吸附动力学遵循准二级速率定律，表明化学吸附是吸附机理的限速步骤。吸附空气…
AbstractA thiacalix[4]arenetetrasulfonate-modified resin has been prepared by loading thiacalix[4]arenetetrasulfonate onto resins for the adsorption of heavy metal ions. Various factors affecting the adsorption capacities such as different resins, resin size, pH, contact time, and temperature were investigated by batch adsorption experiments, and the adsorption isotherms, thermodynamics, kinetics, selectivity, and regeneration were also studied. It was found that the loading capacity of the D201 resin (macroporous strong basic anion exchange resin) for thiacalix[4]arenetetrasulfonate was substantially higher than those of the D301 (macroreticular weak basic styrene anion exchange resin) and the 717 (strong base styrene anion exchange resin) resins and increased with decreasing particle size of the D201 resin. The adsorption kinetics followed the pseudo-second-order rate law for heavy metal ions, indicating that chemical sorption is the rate-limiting step of the adsorption mechanism. The adsorption of heav...
