“…The Cu particles covered the catalytic active sites of the A/R/ACFs, which not only inhibited the light absorption but also prevented the close contact between organic contaminants and photocatalysts. [51] The PSA removal amounts over the A/R/ACFs in the 30 mg/L Cu 2 + group was much lower than those in the 10 mg/L Cu 2 + and 20 mg/L Cu 2 + groups.…”

The effect mechanism of Cu 2 + , Zn 2 + and Ni 2 + ions in wastewater on photocatalytic activity remained unknown. For phenol-4-sulfonic acid (PSA) photodegradation, we fabricated anatase/rutile/activated carbon fiber composites (A/R/ACFs) by the hydrothermal deposition of rutile TiO 2 nanorods and anatase TiO 2 nanoparticles on ACFs. A/R/ACFs exhibited better photocatalytic activity than both R/ACFs and A/ACFs because anatase/rutile heterojunctions supported electron transfer from rutile to anatase. All Cu 2 + , Zn 2 + and Ni 2 + ions in wastewater improved the chemical stability of PSA by forming PSA-Cu(II), PSA-Zn(II) and PSA-Ni(II) complex compounds, and thus inhibited the PSA photodegradation. Notably, the as-formed photoelectrons over A/R/ACFs were partly consumed due to the reduce reaction of Cu 2 + ions into Cu + /Cu 0 , avoiding electron-hole recombination and improving PSA photodegradation efficiency. No reduce reaction of Zn 2 + and Ni 2 + ions occurred during the PSA photodegradation process. Hence, the A/R/ACFs are an effective photocatalyst for wastewater purification, and low Cu 2 + concentrations facilitated the PSA photodegradation.

“…The Cu 2p 3/2 peak was at 933.78 eV and the Cu 2p 1/2 peak was at 953.50 eV aer the adsorption of Cu(II), 7 indicating that BC-NH2 can successfully adsorb Cu(II); in addition, strong shaking satellite lines appeared at 940-945 eV. 50 The N 1s spectrum consisted of three tted peaks, including amide N-H, C-N and -NO 2 centered at 400.04 eV, 402.17 eV and 406.07 eV binding energies were centered. Both the C and N peaks shied, indicating that both atoms are involved in the adsorption process.…”

“…These diseases spread rapidly and cause huge economic losses once outbreak becomes endemic. Consequently, antibiotics such as sulfonamides and tetracyclines, have been widely used to prevent livestock diseases (Shao et al 2020). At the same time, heavy metals including zinc and copper have also been extensively used as feeding additives to increase production ).…”

The complex mixtures of antibiotics and heavy metals are commonly existed in livestock and poultry breeding wastewater. Effective and simultaneous removal of these toxic compounds by microorganisms, especially single strains remains a considerable challenge. In this study, a novel functional strain SDB4, isolated from duck manure and identi ed as Bacillus sp., has been shown to possess high removal abilities for both sulfamethoxazole (SMX) and Zn 2+ . The maximum removal e ciency achieved 73.97% for SMX and 84.06% for Zn 2+ within 48 h in sole system. It has great potential for eliminating SMX along with Zn 2+ , 78.45% of SMX and 52.91% of Zn 2+ were removed in the 20 mg•L -1 SMX and 100 mg•L -1 Zn 2+ binary system. Furthermore, the SMX-biotransformation ability of SDB4 was enhanced at low concentrations of Zn 2+ (below 100 mg•L -1 ). N 4 -acetyl-SMX was identi ed as the main stable transformation product during SMX bioremoval. FTIR analyses revealed that OH, NH 2 , C=O, C-N/N-H and C-O-C played major roles in the biosorption of Zn 2+ . Our study of the dually functioning strain SDB4 provides a potential application for the simultaneous biological removal of antibiotics and heavy metals.
