壳聚糖基纤维膜制备及离子吸附性能研究
Research on the Preparation of Chitosan-based Fiber Membranes and Their Ion Adsorption Performance
摘要
Abstract
The adsorbent adsorption method is one of the important ways to remove heavy metal ions from wastewater.In this paper,chitosan(CS)and polyethyleneimine(PEI)were introduced into the polymethyl methacrylate(PMMA)matrix and the novel CS/PMMA/PEI nanofiber membranes were prepared by electrospinning.The CS/PMMA/PEI nanofiber membranes had a uniform diameter of approximately 900 nm,which exhibited good hydrophilicity and thermal stability.Their adsorption effect and mechanism on Cu(Ⅱ)ions were systematically explored.The CS/PMMA/PEI nanofiber membranes showed high Cu(Ⅱ)ion adsorption capacity(83.3 mg/g)and removed Cu(Ⅱ)ions through electrostatic adsorption.Additionally,the nanofiber membranes had abundant amino(-NH2)and hydroxyl(-OH)groups,providing potential adsorption sites for the complexation of Cu(Ⅱ).The CS/PMMA/PEI nanofiber membranes with low-cost raw material and simple preparation method displayed wide-range application prospects in removing heavy metal ions from wastewater.关键词
