The photocatalytic degradation of betamethasone sodium phosphate was investigated in aqueous suspensions of zinc oxide nanoparticular with diameter size 20 nm under a variety of conditions. Different parameters such as irradiation time, the amount catalyst (0.12-0.8 g LH), initial concentration of drug (10-50 mgLjand initial pH values (ranging from 3 to II) were investigated in the presence of various electron acceptors. It was observed that 0.44 gL-I of photocatalyst is the optimum value for photocatalyst dosage. In the most favorite conditions, the degradation efficiency was obtained 30gL-I for betamethasone sodium phosphate. Finally, the kinetics process was studied and the photodegradation rate of betamethasone sodium phosphate was found to obey pseudo-first-order kinetics equation represented by the Langmuir-Hinshelwood model.
