Several composite hydrogels were prepared by in situ incorporation of sugarcane bagasse cellulose (CB) and a natural polymer gelatin (GT) in to the polyacrylic copolymer network by free radical solution polymerization. The hydrogels were characterized by FTIR, XRD, TGA, DMA, SEM, EDAX, pH at point zero charge and swelling reversibility at varied pH in water. The effects of the synthesis parameters on sorption of Cu (II) from water by the resulting hydrogels were studied and the results were optimized by response surface methodology (RSM) with Box-Behnken design (BBD). The hydrogel prepared with optimized parameters was further studied for sorption of Cu (II) at varied process conditions.
通过自由基溶液聚合将甘蔗渣纤维素（CB）和天然聚合物明胶（GT）原位掺入聚丙烯酸共聚物网络中，制备了几种复合水凝胶。通过傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、热重分析（TGA）、动态热机械分析（DMA）、扫描电子显微镜（SEM）、能量散射X射线光谱（EDAX）、零电荷点pH值以及在不同pH值水中的溶胀可逆性对水凝胶进行了表征。研究了合成参数对所得水凝胶从水中吸附Cu（II）的影响，并通过采用Box-Behnken设计（BBD）的响应面法（RSM）对结果进行了优化。对在优化参数下制备的水凝胶在不同工艺条件下对Cu（II）的吸附进行了进一步研究。
