Preparation of Electrospinning Polystyrene Nanofibrous Membrame and Nanofiltration for Simulated Dyeing Wastewater
In this thesis, polystyrene nanomembranes made by electrospinning technique were utilized to deal with Cu2+(5mg/l), Cr6+(5mg/l) and methylene blue (10mg/l) contained in simulated dyeing wastewater. Polystyrene liquor (8% (m/m), dissolved in chloroform) was electrospun and processed nanofibrous membrane; the nanofiber diameter was 250nm~15µm; the detected pore size was 3nm~0.5µm and the membrane thickness was 170µm. A plate membrane system was used to test nanofiltration characteristics of pollutants (Cu2+, Cr6+ and methylene blue). The experiment showed that the interception rates were above 91%, and the water flux was about 5.8-15.4ml/ (cm2h).
