“…According to previous studies, EtOH and TBA were commonly used as scavengers of OH and SO 4 À , and OH, respectively. 14,32 The molar ratio of alcohol to sulfite was set to 500 : 1, namely the concentration of EtOH and TBA was calculated to be 1.0 M according to our previous research. 8 As presented in Fig.…”

“…[ 18,19 ] The biological methods are based on the metabolic degradation of phthalates by microorganisms under aerobic or anaerobic conditions. [ 10,20,21 ] In the literature, we did not find any study devoted to the degradation of phthalates in the gas phase, which is the objective of the present study.…”

“…[ 7,8 ] The European Union has classified some phthalates (e.g., DMP, DEP, DBP, DEHP, and benzyl butyl phthalate [BBP]) as the main environmental pollutants. [ 9,10 ] Phthalates are stable at ambient temperature and can be found almost everywhere, in the atmosphere, water, soil, plants, and aquatic organisms, and they have become one of the most ubiquitous environmental pollutants, which threaten food security and biohealth and alter the genetics of living organisms. [ 11,12 ] Therefore, it is essential and urgent to develop appropriate methods for the treatment of phthalates in water, air, and soil.…”

Ion mobility spectrometry was used to monitor the degradation of phthalate vapors by corona discharge. Three different phthalates (dimethyl [DMP], diethyl [DEP], and dipropyl [DPP]) were examined in a corona discharge reactor (wire‐to‐cylinder geometry) at direct current positive polarity in ambient air. The relative removal efficiencies up to 96% and energetical degradation efficiencies of 229.27, 216.12, and 198.84 kJ mg−1 were achieved for DMP, DEP, and DPP, respectively. Byproducts such as methanol, ethanol, and 1‐ and 2‐propanol at extremely low densities were also detected. The identified degradation processes involved two steps: (i) An electron‐impact dissociation of phthalates into alkoxyl radicals and (ii) reactions of alkoxy radicals with water molecules to form alcohols.

“…Apart from this, Anbia et al [ 18 ] reported that Fe 3 O 4 –copper-functionalized silicon nanowires from silicon powder were utilized as a catalyst for phenol degradation with an efficiency of approximately 100%. Highly doped silicon materials have also been shown to be capable of the post-catalytic degradation of methylene blue and anionic (methyl orange) dyes [ 19 ]. In addition, mine-based active Fenton-like materials have been already reported as capable of degrading TC and other antibiotics in water [ 20 ].…”

Inappropriate disposal of leaching residues from the lead-zinc tailings recovery process may result in environmental pollution. Its recycling and reuse remain a prevalent topic in environmental science and technology. It was roasted to prepare leaching residues-based materials (TLRS) in this work, and the TLRS were creatively used as the catalyst to active sodium persulfate (PS) to degrade organic pollutants. Degradation of tetracycline using the TLRS–PS system was evaluated, and the treating parameters were optimized. Roasting resulted in the exposure of active sites on TLRS surface, in which transition metals can donate electrons to PS to form SO4·−. SO4·− can further react with OH− to form ·OH. Formation of these radicals was confirmed by both quenching experiments and EPR analysis. Under optimized conditions, 85% of the TC can be degraded in 3.0 h, and ~50% of degraded TC was mineralized to CO2 and H2O. The performance of TLRS barely changed after four reuses, suggesting the chemical stability of TLRS. The presence of dissolved substance in the water matrix could weaken the performance of the TLRS–PS system. A mechanism of TC degradation was proposed based on the experimental results and literature. These preliminary results provide us new insight on the reuse of lead-zinc flotation tailings.
