Methylene blue (MB) is a carcinogenic contaminant known for its harmful effects on humans and marine life. This study focuses on the basics and variables of kinetic studies involved in the degradation of MB. It has been seen that TiO2 and ZnO were used as adsorbents and photocatalysts under the effect of sonolysis in the absence and presence of H2O2. Fenton and photo-Fenton reactions under ultrasonic radiation were also used to investigate the degradation of MB dye. These methods successfully degraded the investigated dye by (89.2, 98.2, 87.8, 95.2, 64.5, 97.2, 87.5 and 98 % respectively). The most effective approach is photo-Fenton with ultrasound. The AOPs employed in this study can be used as an acceptable tool for degrading hazardous dyes into non-toxic end products.
