The degradation of cefazolin (CFZ) by Ag3PO4/BiOBr composites under visible-light irradiation was explored. The main and interaction of parameters (catalyst dosage, pH, CFZ initial concentration and degradation time) on removal of CFZ were studied by Box-Behnken design combined with response surface methodology. The pH was the most influential factor and both h+ and ㆍOH played a role in the photocatalytic process. The high correlation coefficients (R2 = 0.9986 and adjusted R2 = 0.9973) demonstrated close fit between the predicted and experimental values. The exceptional efficiency of Ag3PO4/BiOBr composite in removing CFZ represents a promising technique for treatment of CFZcontaining wastewater.
