Application of Cellulose Nanocrystal Based Composite Microbeads in Water Treatment
Cellulose nanocrystals(CNC),as the most abundant biopolymer in the world,is a green,renewable and environmentally friendly material with good adsorbent properties such as high specific surface area and surface active groups,which has high potential application in wastewater treatment.CNC-based composite microbeads are an effective,economical and time-saving material for water treatment.When CNC is compounded with other functional nanoparticles,it can effectively enhance the effect of each component due to its unique prop-erties and adsorption activity,while effectively solving the problem that nanomaterials are difficult to be recycled and cause secondary damage to the environment.This paper reviews the recent literature on the application of CNC-based composite microbeads in water treat-ment,which will provide researchers with guidelines for designing more suitable CNC-based composite microbeads and thus facilitate the research.
