Abstract

As a fast and efficient process, a periodate (PI)-based advanced oxidation process was used to degrade direct red 89 (DR89), wherein hydrogen peroxide (H2O2) was employed to activate PI (H2O2/PI process) to investigate the effect of operating parameters and mixture composition. The PI was efficiently activated by H2O2 to degrade 67% of DR89 within 1 min. Acidic pH was more favorable to high-efficiency degradation than the basic pH; at pH 3 degradation rate was 94.31%, while it was only 20.92% at pH 11. The degradation rates were further enhanced with increasing H2O2 and PI dose up to certain optimum values, later it decreased which was dependent upon the amount of hydroxyl (●OH) and iodyl (IO3●) radicals produced. The quenching experiments suggested that IO3●, ●OH, 1O2, and O2●− are the predominant reactive species during H2O2/PI process, while O2●− radicals are the primary precursor of other reactive oxygen species. The results of this study suggested that H2O2/PI is the efficient and rapid treatment method to degrade persistent organic pollutants (POPs) from polluted wastewater sources. © 2024 Elsevier Ltd
