▎ 摘　　要

Chemically modified graphene oxide (CMGO)/nanohydroxy apatite (nHA) composite was synthesized via a facile chemical modification of graphene oxide (GO) by triethyltetramine (TETA). Band gap of GO could be tuned for photo degradation under visible light through surface modification as well as by the composite formation with nHA. Pseudo-second-order kinetic model related the drug adsorption while degradation process followed first-order kinetics with Sips isotherm as the best fitted model. Feasibility of photo catalyst in the degradation of AM was tested using waste water samples collected from polluted area near to poultry fields and animal farm houses.
