Adsorption characteristics of diclofenac and sulfamethoxazole to graphene oxide in aqueous solution

The adsorptive properties of graphene oxide (GO) were characterized, and the binding energies of diclofenac (DCF) and sulfamethoxazole (SMX) on GO adsorption were predicted using molecular modeling. The adsorption behaviors of DCF and SMX were investigated in terms of GO dosage, contact time, and pH. Additionally, the effects of sonication on GO adsorption were examined. GO adsorption involves “oxygen-containing functional groups” (OCFGs) such...
