The sonochemically synthesized Ho-doped ZnO nanoparticles were characterized by XRD, SEM, TEM,and XPS techniques. The sonocatalytic degradation of Reactive Orange 29 (RO29) was greater than thatwith sonolysis alone. DE% declines with the addition of chloride, carbonate, sulfate, and tert-butanol asradical scavengers. Addition of potassium periodate, peroxydisulfate, and hydrogen peroxide asenhancers improves DE%. The results demonstrate proper reusability of the doped sonocatalyst. Degradation intermediates were identified by gas chromatography–mass spectrometry (GC–MS). Usingnonlinear regression analysis, an empirical kinetic model was developed to predict the pseudo-first-order constants (kapp) as a function of the operational parameters.
