Abstract

谷胱甘肽磁性分子印迹聚合物的制备及吸附性能研究 王茹娟 马应霞 路翠萍 李涛 杜雪岩 * (兰州理工大学 省部共建有色金属先进加工与再利用国家重点实验室 材料科学与工程学院 甘肃 兰州 730050) 摘要 采用表面分子印迹技术, 以谷胱甘肽(GSH)为模板分子, N-乙烯基吡咯烷酮(NVP)和丙烯酰胺(AM)为功能单体, N,N′-亚甲基双丙烯酰胺(MBA)为交联剂, γ-(甲基丙烯酰氧)丙基三甲氧基硅烷(KH570)改性的 Fe 3 O 4 纳米颗粒为磁性载 体, 制备了对 GSH 有特异识别性的磁性分子印迹聚合物(GSH-MMIPs).利用 X 射线衍射仪(XRD)、透射电子显微镜 (TEM)、红外光谱(FT-IR)和振动样品磁强计(VSM)对聚合物进行了表征, 结果表明磁性载体表面成功地包覆了分子印 迹聚合物薄层.静态吸附平衡实验和 Scatchard 分析结果表明, GSH-MMIPs 中存在两类不同的结合位点, 平衡解离常数 分别为 8.786×10
