Water Purification by Polyvinyl Chloride Nanofibers Membrane Filter

Kyaw Myo Zaw*

The objective of this work was to purify wastewater of preparing Polyvinyl Chloride (PVC) nanofibrous membranes by electrospinning with single solvent and their potential applying as affinity membrane. The PVC solutions in dichloromethane (DCM), formic acid and acetic acid were electrospun into nonwoven fiber membranes, respectively. The field emission scanning electron microscope (FEEM) results showed that the as-spun PVC nanofibers using DCM as solvent were continuous and smooth with the fiber diameter ranging from 50-500nm. Furthermore, their properties such as specific surface area, fiber diameter and porosity were investigated. The nanofibrous membranes exhibited high surface area and high porosity compared with commercial filter paper like as patron filter and displayed very high water permeability.
