摘要:
为制备出一种绿色环保、重金属离子吸附性能良好的多孔醋酸纤维素(CA)复合纤维膜,选用天然吸附材料蒙脱土(MMT),以CA为基材,通过离心纺丝技术,设计制备MMT/CA多孔复合纤维膜,并将所得纤维膜应用于重金属离子吸附。采用扫描电子显微镜(SEM)、红外光谱仪(FTIR)、X射线光电子能谱仪(EDS)、热重分析仪(TGA)和原子吸收光谱仪(ASS)对复合纤维的形貌结构及吸附性能进行表征。结果表明:在溶剂DCM/DMSO质量配比8∶2时成功制备出具有多孔结构的MMT/CA复合纤维膜;随着MMT质量分数的增加,其Cu 2+吸附量也随之增大,当质量分数为3%时最大Cu 2+吸附量为44-243 mg/g,并且经过5次解吸循环后,仍保持有80%以上的吸附效果。
