Tian) dSchool of Environmental Science and Engineering, Tianjin University, Tianjin 300072, China Received 25 February 2020; Accepted 25 July 2020 abstract A series of magnetic porous Fe–C materials were prepared by one-step pyrolyzation of ethylene- diaminetetraacetic acid sodium iron(III) at 500°C–800°C and then employed as adsorbents for sulfamethoxazole (SMX) adsorption. The one prepared at 700°C (Fe–C-700) was selected as the opti- mum one with an adsorption amount of 82.3 mg g–1 at pH 5.0 and 30°C.
