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

Chicken eggshells (ESs) consist of 96%–97% calcium carbonate, while about 3%–4% consists organic substances, mainly in the form protein‐based membranes and occluded matter. Recently, ESs have been studied as a filler polymer composite materials, which represents an innovative solution to address ES valorization. In this study, thermal chemical treatments were investigated for membrane removal since may alter various properties when fillers are added material. A nanoindentation method was used measure changes mechanical properties. Scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier‐transform infrared (FT‐IR) spectroscopy characterize through treatment. The results showed that even at heating temperature 100°C, negatively affected, low concentration bleach (25% 10 min holding time) able remove without reducing treatment offers means conserving quality mineral fraction (calcite; CaCO 3 ).
