Aquatic biomass cellulose fabrication into cellulose nanocomposite and its application in water purification

Abstract

The combination of nanotechnology principles and membrane technology has gained more attention in waste water remediation owing to the high efficiency of toxicants removal, unique physico chemical properties and biodegradability. This current work offers a wide and accurate overview of nanocellulose acetate membrane technology for waste water treatment efficacy. In this review, we described nanocellulose acetate membrane synthesis through electrospinning process and its potential role in waste water remediation. In particular, extraction of cellulose from lignocellulosic invasive aquatic weeds biomass wastes, conversion of extracted cellulose into cellulose acetate followed by fabrication with bio active metallic nanoparticles via electrospinning process were discussed. Most significantly, the factors influencing the electrospinng process, efficacy testing methods and the role of water treatment process were described. The present study suggests the sustainable approach of managing hazardous invasive aquatic weeds into composite membrane utilizing green nanotechnology principles with waste water treatment efficacy. In future, the nanocellulose composite that synthesised by the above described green nanotechnology principles can be used in waste water treatment process by showing higher separation or removal of organic and inorganic contaminants with eco-friendly and low operation costs.
