Sugarcane Bagasse as a Biosorbent for Removal of Dyes

Abstract

Organic and inorganic pollutants affecting surface water sources are a serious problem in the developing world, therefore removing these potentially harmful contaminants from the aquatic environment using environmentally friendly methods is important. Biosorption or the passive binding of pollutants in aqueous solutions using dead biomass may be accomplished by utilizing a variety of low-cost agro-industrial wastes, which offer a cost-effective alternative to conventional methods for pollutant removal from aqueous solutions. The application of sugarcane bagasse as a cost-effective natural biosorbent is the focus of this review. The use of Sugarcane Bagasse (SB) biosorbent in both its raw and modified forms for dye removal from wastewater is studied in this article. SB activation and modification approaches were studied using physical, chemical, biological, composite formation, and grafting procedures. Aside from that, the impact of several optimization parameters on the adsorption process, such as adsorbent dose, preliminary dye concentration, pH, temperature, and contact period, was examined. Also discussed dye-loaded SB regeneration problems and solutions. The opportunities for future waste-derived adsorbent research were investigated.
