Synergistic Sonocatalytic Degradation of Sulfasalazine Using Green-Synthesized Nanoscale Zero-Valent Iron: Optimization, Kinetics, and Toxicity Assessment
This study demonstrates that green-synthesized nanoscale zero-valent iron (nZVI) derived from oak leaf extract, when combined with ultrasound and hydrogen peroxide in a sono-Fenton system, effectively degrades sulfasalazine and pharmaceutical wastewater with high efficiency, rapid kinetics, substantial mineralization, and significantly reduced toxicity.
