Hydrogel-based materials as antibacterial agents and super adsorbents for the remediation of emerging pollutants: A comprehensive review
Hydrogels have various potential applications due to their unique characteristics and recently, hydrogels have been utilized as adsorbents in wastewater treatment because of their ability to remove contaminants from water. Constructing strong hydrogels with high adsorption capabilities is crucial for effective wastewater treatment. Scientists and researchers are working to improve the properties of hydrogels by incorporating inorganic elements into polymer networks, which further reduces the costs as well as simplifies their preparation. Natural polymers like starch and alginate are widespread due to their economic and biological advantages, such as biodegradability, biocompatibility, reduced toxicity, environmental friendliness, and low cost. The adsorption of pollutants onto hydrogels as well as their use as antimicrobial agents has garnered significant attention. This review paper summarizes the latest studies on using hydrogels as adsorbents to remove endocrine-disrupting chemicals (EDCs), persistent organic pollutants (POPs), and other emerging pollutants from water environments along with their use as antimicrobial agents. In the first step, different classes of hydrogels and different characterization techniques have been discussed. Next antimicrobial potential of hydrogels is elaborated to understand how these hydrogels can be a potential candidate for such activities. While discussing the adsorption application of hydrogels, different isothermal, kinetics and thermodynamics models have been discussed to highlight the mechanism and nature of forces involved in adsorption of pollutants. Further different simulations such as DFT and MD have been discussed to get more holistic understanding of pollutants adsorption onto hydrogels. A limited number of studies have utilized other techniques such as Monte Carlo simulations and computational fluid dynamics (CFD) so it is important to explore a variety of computational methods to gain a comprehensive understanding of the adsorption process onto hydrogels.
期刊介绍:
Emerging Contaminants is an outlet for world-leading research addressing problems associated with environmental contamination caused by emerging contaminants and their solutions. Emerging contaminants are defined as chemicals that are not currently (or have been only recently) regulated and about which there exist concerns regarding their impact on human or ecological health. Examples of emerging contaminants include disinfection by-products, pharmaceutical and personal care products, persistent organic chemicals, and mercury etc. as well as their degradation products. We encourage papers addressing science that facilitates greater understanding of the nature, extent, and impacts of the presence of emerging contaminants in the environment; technology that exploits original principles to reduce and control their environmental presence; as well as the development, implementation and efficacy of national and international policies to protect human health and the environment from emerging contaminants.
