聚氯甲基化苯乙烯（ PS?CH2 Cl）和间苯二胺（ MPA）在相转移催化剂的作用下，合成聚氯甲基化苯乙烯间苯二胺树脂（ PS?CH2?MPA），研究了PS?CH2?MPA对Pb（Ⅱ）的吸附性能，通过改变溶液的pH值、吸附温度、Pb（Ⅱ）的初始浓度、吸附时间等因素来探究树脂PS?CH2?MPA对Pb（Ⅱ）的吸附效果，实验结果表明，酸性范围内，吸附量随着pH的增加而增加，pH＝6时，吸附效果最佳；PS?CH2?MPA对Pb（Ⅱ）的吸附速率较快， t＝60min即可基本达到平衡；吸附过程能较好的吻合Freundlich等温吸附模型，且是放热过程，高温不利于吸附；对PS?CH2?MPA进行吸脱附实验，其吸附性能并未下降，是一种可以重复使用的吸附剂，所有结果表明PS?CH2?MPA在吸附Pb（Ⅱ）方面有着广阔的应用前景。
A novel chelating material (PS?CH2Cl?MPA) was prepared by reacting chloromethylated copolymer of styrene?divinylbenzene (PS?CH2Cl) with m?phenylenediamine (MPA) in the presence of phase transfer catalyst. Adsorption activities of PS?CH2?MPA for Pb (Ⅱ) from sewage were investigated with regard to contact time, pH, the initial Pb (Ⅱ) concentration and temperature. The results revealed that the adsorption capacity of PS?CH2?MPA was effected by the acidity of solution, maximum adsorption was observed at pH=5;Initial rate was very rapid and gradually slowed down, it can be inferred that the equilibrium reached when t = 60min; The adsorption data followed Freundlich model. Moreover, lower temperature was preferable for adsorption since it was exothermic;The adsorption for re?adsorption of PS?CH2?MPA has no degradation, the adsorbent can be reused; Therefore, PS?CH2?MPA is an effective adsorbent for the removal of Pb (Ⅱ) from sewage.
