ABSTRACT The present study proposes development of an adsorbent based on combination of graphene oxide (GO) and iron oxide (α-γ-Fe2O3) nanoparticles for atrazine removal from water. The synthesized adsorbent (GO@ α-γ-Fe2O3) was characterized using different techniques. Magnetic measurements proved that the adsorbent has superparamagnetic characteristics, thus facilitating its magnetic separation from the working suspensions. The maximum adsorption capacity was 42.5 mg g−1. The Langmuir isotherm and the pseudo-second order kinetic models correlated adequately with the experimental data. The thermodynamic data showed that atrazine adsorption was spontaneous, endothermic and thermodynamically favorable.
