文章以D301树脂为载体，先通过表面接枝聚合法将甲基丙烯酸缩水甘油酯(GMA)接枝到D301表面，再经胺化、磷酸化反应制备出磷酸改性树脂(PAD301)。采用扫描电子显微镜、傅里叶变换红外光谱等手段对PAD301树脂进行表征，研究磷酸改性条件对其吸附性能的影响，并考察了PAD301对Pb2+的吸附行为。结果表明：PAD301适宜的磷酸改性条件为亚磷酸与NH2摩尔比8∶1、多聚甲醛与NH2摩尔比8∶1、盐酸与NH2摩尔比4∶1，反应温度为80℃，反应时间为10 h；在此条件下制得的PAD301对Pb2+的吸附量可达175.2 mg/g，且具有优良的再生与重复使用性能。
Abstract：The article takes D301 resin as the carrier. Firstly, glycidyl methacrylate(GMA) is grafted onto the surface of D301 through surface graft polymerization. Then, the phosphoric acid modified resin(PAD301) is prepared through amination and phosphorylation reactions. The PAD301 resin is characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and other means. The influence of the phosphoric acid modification conditions on its adsorption performance is studied, and the adsorption behavior of PAD301 for Pb2+ is investigated. The results show that the suitable phosphoric acid modification conditions for PAD301 are a molar ratio of phosphorous acid to NH2 of 8∶1, a molar ratio of polyoxymethylene to NH2 of 8∶1, a molar ratio of hydrochloric acid to NH2 of 4∶1, a reaction temperature of 80 ℃, and a reaction time of 10 h. Under these conditions, the adsorption capacity of PAD301 for Pb2+ can reach 175.2 mg/g, and it has excellent regeneration and reusability.
