Spent Bleaching Earth (SBE) that has been impregnated with WO 3 can degrade methylene blue through sonocatalytic. The stages of this research are SBE preparation, activation, WO 3 -SBE modification through wet impregnation process and sonocatalytic test. WO 3 -SBE is characterized using SEM and XRD. In the SEM results, there are cavities in the surface morphology of SBE after activation and after impregnation, the cavities are covered. WO 3 -SBE XRD diffraction pattern shows the presence of WO 3 at an angle of 2θ = 28.855°; 34,813°. The percentage of degradation of methylene blue was 99.12%, using 0.15 grams catalyst, 100 ppm concentration and 15 minutes contact time.
