Homogenous UV/Periodate Process for the Treatment of Acid Orange 10 Polluted Water

The photoactivated periodate (UV/IO4−) process is used to investigate the degradation of acid orange 10 (AO10) dye. photodecomposition ions produces highly reactive radicals (i.e., •OH, IO3•, and IO4•) that accelerate dye degradation. Increasing initial concentration 3 mM enhances removal rate, but over periodate, rate slows down. On contrary, increasing concentrations reduces performance. pH most critical factor in AO10 breakdown. Salts slow down However, UV/IO4− more efficient distilled water than natural water. Even at low concentrations, surfactants may affect dye’s decomposition rate. addition sucrose reduced breakdown AO10. Although tertbutanol a very effective •OH radical scavenger, it does not even highest concentrations. Accordingly, non-•OH pathway route. According retrieved data, method eliminated 56.5 60.5% COD after 60 120 min treatment time; therefore, can be concluded system treat effluents, especially those containing textile dyes.
