Research Progress of Electrospun Fiber Membrane in Water Treatment
With the rapid development of economy,environmental pollution has become a serious problem that must be solved.Water is the source of life,but now it is seriously polluted.In recent years,nanofiber membranes have been widely used in water pollution treatment.This is mainly because it has the characteristics of easy preparation,high porosity and easy recovery,which is the defect of traditional processing technology to be improved.At present,the main methods for preparing nanofiber membranes are molecular technique,spinning method and biological method.Among them,electrospinning is a popular technique for preparing nanofibers.The porous,highly permeable and highly ordered nanofiber membrane can be obtained by electrospinning,and the metal ions,harmful bacteria and organic pollutants in water can be well removed by membrane separation.In this paper,the application and future improvement of electrospun nanofiber membrane in removing main pollutants such as dyes,metal ions,oil,antibiotics and bacteria in water are reviewed.
