Rationally designed carboxymethylcellulose-based sorbents crosslinked by targeted ions for static and dynamic capture of heavy metals: Easy recovery and affinity mechanism

Synthesis of bagasse-derived carboxymethyl cellulose aerogels for efficient removal of cationic dyes and heavy metal ions

“…7 Casaburi et al reported the synthesis of CMC through Williamson etherification, but neither of these studies explored its application. 8 In biodegradable derivatives of CMC with excellent gel-forming characteristics, hydroscopicity, and non-toxicity, 9 owing to the high DS, carboxyl groups can offer a variety of adsorption sites for MB and metal ions. 10 The large number of carboxyl groups was beneficial for the adsorption of MB in the study conducted by Eltaweil et al 11 Aerogels can also be used to remove pollutants from wastewater owing to their unique properties of high surface areas and a 3D interconnected porosity.…”
