Highly efficient persulfate oxidation process activated with Fe0 aggregate for decolorization of reactive azo dye Remazol Golden Yellow

Abstract: The commercially available Fe 0 aggregate has advantages of low-cost, fast-effective decontamination, reusability, and ease of operation. However, little study has been done on the performance of Fe 0 aggregate as a catalyst in degradation of azo dyes, particularly used in persulfate (PS) oxidation process. This study investigated decolorization of a reactive azo dye, Remazol Golden Yellow (RGY, Reactive Orange 107), by persulfate oxidation activated with Fe 0 aggregate. RGY decolorization was not effective in… Show more

“…2,3 Among the physicochemical technologies, advanced oxidation technologies, such as activated persulphate oxidation, have been developed and successfully used for the degradation of colorants. [4][5][6][7][8] Compared with physicochemical methods, biotechnology is more efficient for organic pollutant reduction, providing a better developed application in the treatment of textile dyeing wastewater. However, these conventional treatment technologies also have their own shortcomings that are difficult to overcome, such as the consumption of additional chemical reagents, a low decolorisation rate and poor desalination efficiency.…”

“…This inhibition arises from the rapid consumption of both SO • and •OH radicals owing to the scavenging role of bicarbonate in the solution [55]. A previous report by Weng et al [56] described that the presence of bicarbonate induced Fe-complex formation in the solution, affecting the availability of Fe 2+ for the production of SO • radicals to oxidize compounds in the Fe 2+ /PS system, hence, the degradation efficiency of MB 9 was reduced.…”

“…Among these transition metals, Fe has often been selected as a PS activator owing to its low toxicity, low cost, high activity, and natural abundance [15]. However, the Fe/PS system has some intrinsic drawbacks, such as strict pH range limits and accumulation of ferric oxide sludge, which limit its widespread application [16][17][18].…”
