Peroxydisulfate (PDS) is an appealing oxidant for contaminated groundwater and toxic industrial wastewaters. Activation of PDS necessary application because its low reactivity. Present activation processes always generate sulfate radicals as actual oxidants which unselectively oxidize organics halide anions reducing oxidation capacity producing halogenated products. Here we report that copper oxide (CuO) can efficiently activate under mild conditions without radicals. The PDS/CuO coupled...
This is the first report on environmental occurrence of a chlorinated polyfluorinated ether sulfonate (locally called F-53B, C8ClF16O4SK). It has been widely applied as mist suppressant by chrome plating industry in China for decades but evaded attention research and regulation. In this study, F-53B was found high concentrations (43-78 65-112 μg/L effluent influent, respectively) wastewater from city Wenzhou, China. not successfully removed treatments place. Consequently, it detected surface...
Cobalt-mediated activation of peroxymonosulfate (PMS) has been widely investigated for the oxidation organic pollutants. Herein, we employ cobalt-doped Black TiO2 nanotubes (Co-Black TNT) efficient, stable, and reusable activator PMS degradation Co-Black TNTs induce by itself stabilized oxygen vacancies that enhance bonding with provide catalytic active sites activation. A relatively high electronic conductivity associated coexistence Ti4+ Ti3+ in TNT enables an efficient electron transfer...
Efficient, inexpensive, and stable electrode materials are key components of commercially viable electrochemical wastewater treatment system. In this study, blue-black TiO2 nanotube array (BNTA) electrodes prepared by self-doping. The 1-D structure, donor state density, Fermi energy level position critical for maintaining the semimetallic functionality BNTA. structural strength BNTA is enhanced surface crack minimization, reinforcement BNTA-Ti metal interface, stabilized a protective...
Electrochemical systems are an attractive option for onsite latrine wastewater treatment due to their high efficiency and small footprint. While concerns remain over formation of toxic byproducts during treatment, rigorous studies examining byproduct lacking. Experiments treating authentic variable times, current densities, chloride concentrations, anode materials were conducted characterize identify conditions that minimize formation. Production inorganic (chlorate perchlorate) indicator...
A rapid (1.5 h) one-step ball milling (BM) method was developed not only to modify commercial MnO2 via top-down approaches (BM0), but also bottom-up synthesize MnOx by cogrinding of KMnO4 and MnC4H6O4 (BM1) or MnSO4 (BM2). Catalysts activity on gaseous POPs removal tested using hexachlorobenzene (HCBz) as surrogate. Catalytic performance decreases in the order BM2 ≈ BM1 (T90% = 180–200 °C) > BM0 (260 CMO cryptomelane (>300 °C). Both adsorption destruction contribute HCBz at 180 °C while...
TiO2 has long been recognized as a stable and reusable photocatalyst for water splitting pollution control. However, it is an inefficient anode material in the absence of photoactivation due to its low electron conductivity. To overcome this limitation, series conductive nanotube array electrodes have developed. Even though arrays are effective electrochemical oxidation initially, deactivation often observed within few hours. problem deactivation, we synthesized cobalt-doped Black-TiO2...
Abstract The activation of persulfates to degrade refractory organic pollutants is a hot issue in advanced oxidation right now. Here, it reported that single‐atom Fe‐incorporated carbon nitride (Fe‐CN‐650) can effectively activate peroxymonosulfate (PMS) for sulfamethoxazole (SMX) removal. Through some characterization techniques and DFT calculation, proved Fe single atoms Fe‐CN‐650 exist mainly the form Fe‐N 3 O 1 coordination, exhibited better affinity PMS than traditional 4 structure....
Multilayer heterojunction SbSn/CoTi/Ir anodes, which consist of Ir0.7Ta0.3O2 bottom layers coated onto a titanium base, Co-TiO2 interlayers, and overcoated discrete Sb-SnO2 islands, were prepared by spray pyrolysis. The layer serves as an Ohmic contact to facilitate electron transfer from semiconductor the Ti base. interlayer islands enhance evolution reactive chlorine. surficial also serve sites for free radical generation. Experiments coupled with computational kinetic simulations show...
