Abstract
electrostatic interactions, hydrogen bonding, and chelation mechanisms. This review provides an overview of the use of chitosan-based aerogels as eco-friendly gels to remove different contaminants from water such as dyes, heavy metals, microorganisms, and pharmaceuticals, by improving the mechanical strength, decreasing hydrophilicity, and increasing acid stability. These improvements are accomplished using different modification methods, such as blending with nanofillers, chemical and/or ionic crosslinkers, and designing composite aerogels. The modified aerogel exhibits excellent adsorption ability against different contaminants, as well as antibacterial properties, making it promising candidates for a wide range of applications.
