The photocatalytic removal of amoxicillin (AMX) over a TiO2/Ge composite under ultraviolet-A irradiation was investigated in this study. The optimal composition of the TiO2/Ge composite was determined by the response surface method to maximize AMX removal and the reduction of toxicity in the aqueous phase; the photocatalytic degradation of AMX over the optimal TiO2/Ge composite was approximately 91.6%.
