In the present paper, the porous carbon material derived from waste PET was fabricated using a one-step recyclable MgO template synthesis approach. The material was subsequently employed as adsorbent for the efficient capture of o-nitrophenol (ONP) from aqueous solutions. With the change of the ratio of MgO template to waste PET, the prepared porous carbon has controllable specific surface area. The sample of WPC-1.5 exhibits a remarkable specific surface area of 885.99 m2/g. Static adsorption experiments demonstrate that this material possesses a substantial adsorption capacity for ONP, achieving a value of 474 mg/g. The WPC-1.5 was characterized by scanning electron microscopy, BET and adsorption kinetic and equilibrium isotherms evaluation.
