| dc.description.abstract | Spent Bleaching Earth (SBE) that has been impregnated with WO3 can degrade
methylene blue through sonocatalytic. The stages of this research are SBE preparation,
activation, WO3-SBE modification through wet impregnation process and sonocatalytic test.
WO3-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.
WO3-SBE XRD diffraction pattern shows the presence of WO3 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. | en_US |
