In order to achieve the goal of phosphate removal from glyphosate by-product salts, zirconium and zinc ions were successfully loaded onto D202 resin by co-precipitation modification method in this study, their effectiveness was evaluated under various conditions. The results static adsorption experiments showed that Zr/Zn@D202 effectively reduced concentration salts 10 mg/L less than 0.1 mg/L, which met national level emission standard (

ABSTRACT The removal of nitrate and phosphate ions from water bodies is essential to reduce eutrophication health hazards. In the present study, a hybrid polymer nanocomposite has been developed for adsorptive wastewater. preparation achieved by microwave irradiation aqueous mixture chitosan (CS), poly(diallyldimethylammonium chloride) (PDADMAC), N‐(2‐hydroxyethyl)acrylamide (HEAAm) N,N′‐methylenebis(acrylamide) (MBA) in presence radical initiator followed incorporation magnetite nanoparticles. A semi‐interpenetrating network (IPN) appears be formed entanglement PDADMAC chains with MBA crosslinked chitosan‐graft‐poly[N‐(2‐hydroxyethyl)acrylamide] within which Fe 3 O 4 nanoparticles are held. materials (CS‐g‐PHEAAm)/PDADMAC (CS‐g‐PHEAAm)/PDADMAC/Fe were characterized their physicochemical structures using FTIR, XRD, SEM, EDS, BET, VSM, TGA techniques. Their utility as adsorbents was evaluated through adsorption studies. process optimized contact time, solution pH, adsorbent dosage, temperature, initial adsorbate concentration. data showed close fit Freundlich isotherm pseudo‐second‐order kinetic models. observed enhance capacity parent IPN significantly value 60.97 65.35 mg g −1 towards 69.93 76.33 phosphate. thermodynamic studies indicated spontaneous endothermic process. regeneration ability along its superparamagnetic biodegradable characteristics makes it material choice absorptive

Drinking and wastewater are to be treated for safe human consumption keeping surface waters clean. There multiple water purification procedures, but the use of ion-exchange resins significantly enhances efficiency. This review was targeted on highlighting concept classification polymeric as well pointing out their real-world applications. Their successful purposes has been linked chemical structure, simplicity operation, accessibility, reusability. Therefore, have used removal a wide range organic inorganic pollutants such pharmaceutical compounds, dyes, matter, metals, many others. Ion-exchange obtained directly by synthesis methods or grafting ionizable groups polymer matrix in order ensure continuous improvement. Furthermore, newly designed take into consideration biodegradability potential towards obtaining ecofriendly compounds.
