Polymer supports for the removal and degradation of hazardous organic pollutants: an overview

Abstract

Over the last decades, the presence of highly organic pollutants has increased and become an environmental problem that affects all forms of life. To solve or reduce this problem, multiple strategies have been proposed for the elimination and degradation of organic compounds in aqueous media. This review aims to revise and critically discuss the most recent advances in polymer supports to be used for the adsorption and degradation of organic pollutants. However, the greatest challenge with respect to this issue is the industrial scale‐up of bioremediation processes that allow the removal and degradation of compounds in a continuous and large‐scale manner. © 2019 Society of Chemical Industry

Biologically Enhanced Coagulation–Ultrafiltration Process for Healthy Water Production with Low Fouling Propensity

“…The reduction of TTHMFP via direct UF likely resulted from the removed biopolymers, and the adsorption of organics on the biopolymer matrix formed on the UF during filtration, primarily via nonbonding interactions. 66 It was evident that coagulation was inefficient in reducing TTHMFP, which can be ascribed to the limited ability of coagulation to remove NOM in the raw water. After GUSB treatment, the TTHMFP was greatly decreased to approximately 92.81% to 109.32 ± 1.62 μg/L, which was higher than the DOC removal efficiency (73.69%).…”

Hairy silica nanosphere supported metal nanoparticles for reductive degradation of dye pollutants

“…[15][16][17][18][19] However, the direct utilization of MNPs in a liquid-catalysis process has been limited by their irreversible agglomeration and time-consuming separation. 20,21 To address this issue, one of the most effective routes is immobilization of MNPs on solid supports such as polymers, [22][23][24][25] mesoporous silica, [26][27][28] metal-organic frameworks (MOFs), 29,30 carbon, [31][32][33][34] bers, 35,36 and metal oxides, 37,38 which may improve their dispersity and stability. 39 Among these nanostructures, silica nanospheres are deemed as good candidates for MNP catalyst supports due to their uniform spherical geometry, and good chemical stability.…”

Coordination of Lead (II) and Cadmium (II) Ions to Nylon 6/Flax Linum Composite as a Route of Removal of Heavy Metals

“…PA6 and Flax Linum has been combined to form a polymer composite. Over the past decades, synthetic polymers have been used as an adsorbent for the study of removal of toxic contaminants from wastewater [6]. Nylon 6 (PA6) or polyamide is one of the upcoming synthetic polymers in heavy metals remediation [7].…”
