Study on inorganic oxidants assisted sonocatalytic degradation of Resazurin dye in presence of β-SnWO₄ nanoparticles

This work presents about the study of inorganic oxidants assisted sonocatalytic degradation of Resazurin (RZ) dye in the presence of β-SnWO₄ nanoparticles. The catalysts were synthesized via a surfactant free sonochemical method. Physical properties of the as-prepared β-SnWO₄ nanoparticles were analyzed by XRD and FE-SEM. The dispersion property and particle size were analyzed by Zeta potential and Particle size analyzer. The degradation of RZ was analyzed in the presence and absence of common oxidants such as PMS (peroxymonosulfate) and H₂O₂ (hydrogen peroxide). The result shows that the RZ was first mineralized to Resorufin and it was degraded to simple molecule in the presence of β-SnWO₄. 75% of degradation efficiency was achieved in presence of β-SnWO₄, while in addition of H₂O₂ and PMS, the efficiency was increased up to 93% and 85% respectively. Our results will pave a new opening in degradation of poisonous dye using inorganic common oxidants.
