This study reported the results of photocatalytic degradation of reactive red 120 dye (RR120) in water using ZnO nanoparticles (UZn) fabricated from one-step sonochemical method. The as-product UZn were characterised using X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The photodegradation of RR 120 has been investigated in the presence of UZn under UVA light irradiation. The effects on photocatalytic process such as the influencing factors of pH, absorbent dosage, initial dye concentration also were studied. The results showed that the photodegradation under optimum conditions of pH9, UZn dose = 300 mg and 120 minutes.
