Nanocellulose-based Hydrogels: Preparation Strategies, Dye Adsorption and Factors Impacting
NANOFABRICATION(2023)
摘要
The improper disposal of dyes without any prior treatment is one of the main causes of water pollution around the globe. Since dye-contaminated water contains a variety of hazardous elements, which may harm the aquatic ecosystem, impact the aquatic organisms and ultimately enter the food web chain. The most effective ways to recycle dye-contaminated waste water are adsorption, electrolysis, advanced oxidation, etc. Out of these techniques, adsorption strategy, due to its superior physico-chemical features, has been preferably em-ployed for treating polluted water. In this review article, the po-tential of pure nitrocellulose (NC) hydrogel, metal/metal oxide or photo-adsorbents-based, metal-organic-framework supported, surface functionalized, bio-materials filled NC-based hydrogels for dyes adsorption has been thoroughly reviewed. The impact of different factors such as pH, time, temperature and filler/ additives on dye adsorption/degradation capability of NC-based adsorbents, and kinetic and isotherm data of dye adsorption has been assessed systematically. Further, the influence of differ-ent eluents on the recycling ability of various NC-based hydro-gels has also been fully assessed.
