中文摘要：

甲基丙烯酸缩水甘油酯（GMA）与双丙酮丙烯酰胺（DAAM）发生共聚,生成一种含环氧基和DAAM亲水链节的PGMA-DAAM共聚物,再与三乙烯四胺反应,合成了一种多胺改性的PGMA-DAAM树脂（TETA-PGMA-DAAM）。树脂的结构经元素分析、红外光谱和热重分析进行表征。探讨了合成树脂对Pb^2＋的吸附性能,考察了吸附温度、pH、金属离子浓度等因素对吸附效果的影响。结果表明,树脂对Pb^2＋的吸附量随着温度的升高而略有增大,在pH约为4.7、温度为40℃和Pb^2＋平衡浓度为0.01299 mol/L时其最高吸附量可达到1.581 mmol/g。树脂对Pb^2＋的吸附符合Boyd模型,表现为液膜扩散控制,其扩散系数在30℃和35℃时分别为0.0131 min-1和0.0175 min-1。吸附过程符合Langmuir和Freundlich等温吸附式。吸附热力学参数ΔG,ΔH和ΔS分别为-3.912 k J/mol（25℃）、2.058 k J/mol和20.025 J/mol,表明吸附过程为自发进行的吸热过程。

英文摘要：

The copolymer with sufficient epoxy groups and hydrophilic DAAM segments was obtained via copolymerization of glycidyl methacrylate（ GMA） and diacetone acrylamide（ DAAM）,named as PGMA-DAAM.The final resin was yielded via modification with triethylene tetramine（ TETA） on the basis of PGMA-DAAM,named as TETA-PGMA-DAAM. The structure and components of TETA-PGMA-DAAM resin were investigated by elemental analysis,infrared spectrum analysis and thermogravimetric analysis. The adsorption performances of Pb^2＋ on the resin were discussed in detail,including adsorption temperatures,pH values and various concentrations of Pb^2＋. The optimal adsorption capacity was 1. 581 mmol / g under the conditions that equilibrium concentration of Pb2 ＋was 0. 01299 mol / L,pH was 4. 7 and temperature was 40℃. Boyd model was better to describe the adsorption mechanism. Film diffusion was the key procedure during the adsorption process and the diffusion were 0. 0131 and 0. 0175 min- 1,respectively at 30℃ and 35℃. Langmuir and Freundlich models were appropriate to apply to the adsorption process. Three thermodynamic parameters of adsorption ΔG,ΔH and ΔS were calculated to be-3. 912 k J / mol（ 25℃）,2. 058 k J / mol and 20. 025 J / k. mol,respectively. The adsorption procedure can proceed spontaneously with endothermic phenomenon.
