Daftar Isi:
- Degradation of methyl orange was carried out with variations in time of 30, 60, 90, 120, 150, 180, 210, 240 minutes and variations in doped catalyst concentrations of 5%, 10%, 15%, 20%, 25% using the photosonolysis method. The results showed that the maximum degradation time of methyl orange was 210 minutes with a degradation percentage of 76.1216%. The variation in the concentration of catalyst for the degradation of methyl orange obtained a maximum concentration of 5% with a degradation percentage of 20.1045%. The band gap value of 5% ZnO-Co catalyst performed using UV-Vis Diffuse Reflectance Spectroscopy (DRS) was 3.21 eV.
