A review on the best bioadsorbent membrane- nanocellulose for effective removal of pollutants from aqueous solutions

Abstract

An irreplaceable and promising resource material, cellulose is one of the most abundant renewable biopolymer found in the biosphere. Its nano counterpart, nanocellulose has also gained wide popularity and interest among researchers throughout the world due its exceptional unique properties like large surface area, good crystallinity and biodegradability. Nanocellulose and its composites have been reported to be the suitable candidates for the remediation of polluted water, degradation of toxic organic compounds, sensors for pathogens in water, adsorbents for oil spill in water and sequestration of CO2 in atmosphere. Here in this review, we have tried to summarize and put together the recent works done and reported on nanocellulose based membranes that are utilized for the removal of different metal ions, dyes, oils, and pharmaceutical components present in aqueous solutions that remain as a threat to the aquatic and human life.
