Fungal biosorption as an alternative for the treatment of dyes in waste waters: a review
Aneeta Sintakindi, Balaprasad Ankamwar
Abstract
Water bodies polluted with toxic dyes have been treated using various separation techniques. Biosorption as a process of adsorption onto biological materials including living and dead is of more consideration recently for pollutant removal. Fungal biosorbents have a great potential in dye removal due to varied functional groups, eco-friendly, cost-effective nature and a continuously used for application from food and industrial fermentation operations. This article discusses the health risk caused by dyes, presents the biosorptive ability of various fungi in dye removal from aqueous solution, reviews the different physico-chemical factors influencing adsorption, kinetic and equilibrium adsorption data and possible mechanisms in the adsorption process.
