Abstract:A new porous self‐precipitating magnetic anion exchange resin (CMIET) doped with γ‐Fe2O3 was prepared by suspension polymerisation and characterized by FT‐IR, TGA, SEM, BET, and VSM. An adsorbent with a rough surface porous structure, enriched with a mesoporous strong magnetic self‐absorbent was obtained. A specific surface area of 19.10 m2/g, a pore volume of 0.2045 cm3/g, a pore size of 36.71 nm exchange capacity of 7.81 mmol/g, and an equilibrium adsorption capacity of up to 46.28 mg/g were measured.
