Abstract

Degradations of methylene blue by sonocatalytic method using Spent Bleaching Earth (SBE) impregnated
with WO3 have carried out. The stages of this study included SBE preparation, activation with H2SO4, modification
of WO3 with SBE through wet impregnation processes and sonocatalytic testing. WO3-SBE was characterized
using XRD. XRD diffraction patterns of WO3-SBE showed the appeareance of WO3 peak at 28.855°; 34.813° 2θ.
The degradation percentage of methylene blue (catalyst weight of 0.15 gram, methylene blue concentration 100
ppm and contact time 15 minutes) was 99.12%.
