| 摘 要： | 以聚四氟乙烯(PTFE)纤维为基质, 以甲基丙烯酸缩水甘油酯(GMA)为单体, 通过辐照接枝聚合制备了PTFE-g-GMA纤维, 用聚乙烯亚胺(PEI)与PTFE-g-GMA纤维进行开环反应制得新型吸附剂PTFE-g-GMA-PEI. 考察了PTFE-g-GMA-PEI吸附剂对溶液中胆红素的吸附动力学、吸附量及pH、离子强度及温度等因素对胆红素吸附的影响. 实验结果表明, 该吸附剂对胆红素有较高的吸附容量及良好的选择吸附性能, 其吸附行为遵循Langmuir吸附模式.

| Abstract: | The adsorbent of bilirubin based on polytetrafluoroethylene(PTFE) fiber was prepared by 60Co radiation-induced graft polymerization with GMA and by subsequent chemical modification of the epoxy group of PTFE-g-GMA fiber with PEI.The highest amino content on the PTFE-g-GMA-PEI fiber is 1.87 mmol /g.The effect of pH,ionic strength,temperature,BSA,initial bilirubin concentration and adsorption dynamics on the adsorption capacity of PTFE-g-GMA-PEI fiber for bilirubin were investigated in a batch system.Experime... |
