Abstract

Magnetic graphene oxide (MGO) was prepared, and characterized using Fourier transform infrared spectroscopy and transmission electronic microscopy. The MGO was used as the sorbent for adsorption of atrazine, and the adsorption performance was investigated under various conditions. Results indicated that the adsorption equilibrium was achieved within 2 h, the adsorption capacity was 7.52 mg/g, and the adsorption process could be well described by Freundlich isotherm model and pseudo-second-order kinetic model. The hexatomic ring as well as carboxyl, carbonyl, epoxy and hydroxy groups on MGO were the main adsorption sites, and there are - interaction and hydrogen -bondÿ interaction of MGO with atrazine. The experimental results showed MGO could be a potential adsorbent for removal of atrazine from aqueous solution.
