Abstract

Novel mesoporous poly(vinyl alcohol)/SiO(2) composite nanofiber membranes functionalized with mercapto groups with diameters of 300-500 nm have been fabricated by a sol-gel electrospinning process; they were highly effective at absorbing Cu(ii) ions from waste water. These nanofiber membranes could be regenerated through acidification.

摘要

通过溶胶-凝胶静电纺丝工艺制备了一种新型介孔聚（乙烯醇）/SiO2 复合纳米纤维膜，该纤维膜经巯基功能化，直径为 300-500nm，对废水中的 Cu(ii) 离子具有高效的吸附性能。这些纳米纤维膜可通过酸化进行再生。
