In order to improve the adsorption capacity of graphene oxide (GO), graphene-based porous carbon (GPC) was synthesized by a two-step activation method. Using chemical activation of microwave exfoliated GO, we obtained GPC with a high Brunauer–Emmett–Teller surface area of up to 1,598 m/g and a large number of micropores. The GPC was firstly used as an adsorbent for the removal of atrazine in aqueous solution. The obtained adsorbent was characterized by scanning electron microscopy, BET, X-ray diffraction, Fourier transform infrared, and Raman spectroscopy. Experimental results indicated that GPC had excellent adsorption capacity (~131.6 mg/g), which was much higher than that of GO synthesized by the Hummer’ method. The adsorption process was more accurately represented by a pseudo-second-order model and Freundlich isotherm model for the adsorption of atrazine on GPC. The present adsorption studies of pesticides revealed the potential of GPC nanomaterial to be utilized as a promising adsorbent for organic pollutants.
