“…Magnetic CuO-Fe3O4 composite is used as a heterogeneous catalyst for phenol degradation by persulfate [193]. A polyhydroquinone (PHQ)-coated Fe3O4/MWCNTs/PHQ catalyst has been used to degrade antibiotic flumequine (FLU) by persulfate oxidation from which two possible pathways are proposed involving hydroxylation, decarbonylation, and ring opening ( Figure 10) [194].…”

“…Typically, PS can serve as a source of sulfate radicals (SO 4 − •) due to its high solubility, good stability, high redox potential (2.01 V) and low cost6. Sulfate radicals (SO 4 − •) can highly effectively degrade various organic contaminants (dyes, phenolics, and antibiotics) in water7.…”

This study investigated the efficiency of nanoscale zero-valent iron combined with persulfate (NZVI/PS) for enhanced degradation of brilliant red X-3B in an upflow anaerobic sludge blanket (UASB) reactor, and examined the effects of NZVI/PS on anaerobic microbial communities during the treatment process. The addition of NZVI (0.5 g/L) greatly enhanced the decolourization rate of X-3B from 63.8% to 98.4%. The Biolog EcoPlateTM technique was utilized to examine microbial metabolism in the reactor, and the Illumina MiSeq high-throughput sequencing revealed 22 phyla and 88 genera of the bacteria. The largest genera (Lactococcus) decreased from 33.03% to 7.94%, while the Akkermansia genera increased from 1.69% to 20.23% according to the abundance in the presence of 0.2 g/L NZVI during the biological treatment process. Meanwhile, three strains were isolated from the sludge in the UASB reactors and identified by 16 S rRNA analysis. The distribution of three strains was consistent with the results from the Illumina MiSeq high throughput sequencing. The X-ray photoelectron spectroscopy results indicated that Fe(0) was transformed into Fe(II)/Fe(III) during the treatment process, which are beneficial for the microorganism growth, and thus promoting their metabolic processes and microbial community.

“…Pharmaceuticals are non-regulated trace organic emerging contaminants that are ubiquitous in the aquatic environment due to discharge of effluents from pharmaceutical industry, hospitals and municipal wastewater treatment facilities (Feng et al 2015, Petrie et al 2015. In most cases, these pollutants are also present in the digested sludge, potentially entailing a high ecotoxicological risk (Martín et al 2012).…”
