以甲基丙烯酸(MAA)为原料,二甲基丙烯酸乙二醇酯(EGDMA)为交联剂,安息香二甲醚为光引发剂,采用紫外光固化方法制备了新型具有褶皱表面的聚(甲基丙烯酸-二甲基丙烯酸乙二醇酯)[Poly(MAA-co-EGDMA)]树脂,利用红外吸收光谱仪(FT-IR)、热重分析仪(TGA)和扫描电镜(SEM)对树脂进行了表征,并将其用于废水中亚甲基蓝染料(MB)的吸附,研究了MB溶液初始浓度、pH值、吸附时间和温度等因素对吸附水中亚甲基蓝的影响。实验结果表明,Poly(MAA-co-EGDMA)树脂对水中亚甲基蓝染料有优异的吸附性能。树脂对亚甲基蓝的吸附过程为放热过程,吸附动力学和热力学行为分别符合准二级动力学模型和Langmuir等温吸附模型。在298K、pH=8的条件下,由Langmuir等温吸附模型计算得到的最大吸附量可达791.35mg/g。
Abstract：A novel of poly(methacrylic acid-co-ethylene glycol dimethacrylate) [Poly(MAA-co-EGDMA)] resin with folded surface was synthesized by UV-radiation curing with methacrylic acid(MAA) as comonomer, ethylene glycol dimethacrylate(EGDMA) as cross-linking agent,benzoin dimethyl ether as photoinitiator. The structure of resin was characterized by Fourier Transform Infrared(FT-IR), Scanning Electron Microscope(SEM) and Thermogravimetric Analysis(TGA). As an adsorbent for methylene blue(MB) from wastewater, adsorption properties were investigated including initial MB concentration, solution pH, contact time and temperature. The experimental results indicated that the Poly(MAA-co-EGDMA) resin prepared by UV curing had excellent adsorption on methylene blue dyes. The adsorption of MB on resin is a spontaneous exothermic process, which is consistent with the second-order adsorption process and equilibrium experiments fitted well the Langmuir isotherm model. The maximum adsorption capacity calculated by the Langmuir isotherm model was 791.35mg/g at pH=8 and 298K.
