Solid-phase extraction of phenols using membranes loaded with modified polymeric resins

Radiation-induced grafting of glycidyl methacrylate onto cotton fabric waste and its modification for anchoring hazardous wastes from their solutions

“…Modification of the grafted cotton fabric with sulfonic acid resulted in introduction of sulfonic acid function which has excellent hydrophilicity and they also give higher recovery than their unmodified analogues [23][24][25][26]. The higher tendency of chemically modified cotton fabric for adsorption of phenol than their unmodified analogues may be attributed to hydrogen bonds [27], which are expected to occur between hydrogen and hydroxyl groups of phenol molecules and the sulfonic acid group on the monomer units of the chemically modified grafted cotton fabric.…”

Chemical Recycling of Expanded Polystyrene Waste: Synthesis of Novel Functional Polystyrene‐Hydrazone Surface for Phenol Removal

“…erefore, attention has been paid to the development of attractive sorbents for removal of phenolic pollutants from wastewater [5]. Different polystyrene based materials such as benzoyl-PS-DVB [6], 2,4-dicarboxybenzoyl-PS-DVB [7], o-carboxybenzoyl-PS-DVB [8], acetyl-PS-DVB [9,10], toluene-PS-DVB [11], diethylenetriamine-PS-DVB [12], sulfonated PS-DVB [13,14], Amberlite XAD-4, and Amberlite IRA96C [15][16][17] have been reported for the removal of phenols and phenolic compounds. In this study, we focus on the novel route for chemical recycling of EPS waste to the new functional polystyrene-hydrazone (PSH) surface for the treatment of phenol contaminated industrial wastewater.…”

Evaluation of β-Cyclodextrin Bonded Silica as a Selective Sorbent for the Solid-Phase Extraction of 4-Nitrophenol and 2,4-Dinitrophenol

“…These materials show some superior characteristics over conventional SPE materials, such as alkyl-bonded silica. Functionalized polymeric sorbents, 11,12 highly cross-linked polymers, [13][14][15] graphited carbon black [16][17][18] and molecular imprinted polymers (MIPs) [19][20][21] are examples of such materials that can offer high efficiency and good recoveries in extracting polar compounds.…”
