Electrospun Nanofibrous Membranes as Potential Adsorbents for Textile Dye Removal-A review

Abstract

Textile wastewaters due to the toxic effects of dyestuffs and other organic compounds and theirstability toward light and oxidizing agents have led to an environmental problem. Several treatmentmethods for dye removal have been investigated. Membrane process is one of the simplest and mosteffective methods for dye removal from industrial wastewaters. Electrospun nanofibrous membranes havehigh specific surface area, high porosity, and small pore size. Therefore, they have been suggested asexcellent candidates for many applications, especially in wastewater treatment. In this paper, we introducethe fundamental aspects of electrospun nanofibrous membranes and their properties, as well as highlightthe enormous potential of nanofibrous membrane as adsorbents for textile dye removal. Finally,characteristic parameters for membrane performance are enumerated. Permeation flux, rejection,membrane porosity, permeability, molecular weight cut off, and decolorization are considered to be themost important ones.
