Efficient rural sewage treatment with manganese sand-pyrite soil infiltration systems: Performance, mechanisms, and emissions reduction.

The application of soil infiltration systems (SISs) in rural domestic sewage (RDS) is limited due to suboptimal denitrification resulting from factors such as low C/N (<5). This study introduced filler-enhanced SISs and investigated parameter impacts on pollutant removal efficiency and greenhouse gas (GHG) emission reduction. The results showed that Mn sand-pyrite SISs, with hydraulic load ratios of 0.

Preparation of multilayer strontium-doped TiO/CDs with enhanced photocatalytic efficiency for enrofloxacin removal.

Multilayer strontium-doped TiO/carbon dots (CDs) materials (TC) were produced via sol-gel-layered carbonization method. A thorough analysis of the fabricated composites via XRD, SEM, and XPS revealed that strontium ions, TiO and CDs, were combined with each other to form layered structures. According to the UV-Vis diffuse reflectance spectrograms and (αhv) vs.

Synthesis of Ag/BiOBr/CeO composites with enhanced photocatalytic degradation for sulfisoxazole.

A novel Ag/BiOBr/CeO composite was successfully prepared for the first time, which had excellent performance in degrading sulfisoxazole (SSX) under visible light irradiation. The as-prepared samples were characterized by SEM, XRD, UV-vis DRS and BET et al. The composite of 10% Ag/BiOBr/CeO showed the best photocatalytic activity and more than 99.

[Preparation of pg-CN/BiOBr/Ag Composite and Photocatalytic Degradation of Sulfamethoxazole].

A pg-CN/BiOBr/Ag composite was successfully prepared by simple high-temperature calcination and co-precipitation methods. The composite was characterized by means of XRD, SEM, TEM, XPS, UV-Vis, BET, and photocurrent analyses alongside other detection methods, and the degradation of 10 mg·L sulfamethoxazole was investigated under simulated visible light irradiation. The results showed that the pg-CN/BiOBr/Ag composite had the best degradation effect on sulfamethoxazole when the loading ratio of silver was 5%.

Enhanced activation of peroxydisulfate by strontium modified BiFeOperovskite for ciprofloxacin degradation.

A series of Sr-doped BiFeO perovskites (BiSrFeO, BSFO) fabricated via sol-gel method was applied as peroxydisulfate (PDS) activator for ciprofloxacin (CIP) degradation. Various technologies were used to characterize the morphology and physicochemical features of prepared BSFO samples and the results indicated that Sr was successfully inserted into the perovskites lattice. The catalytic performance of BiFeO was significantly boosted by strontium doping.

Enhanced degradation of atrazine by nanoscale LaFeCuO perovskite activated peroxymonosulfate: Performance and mechanism.

Cu-doped LaFeO perovskite (LaFeCuO, LFC) synthesized using a sol-gel method was introduced in the heterogeneous activation of peroxymonosulfate (PMS) for atrazine degradation. The obtained LFC catalysts were characterized by several technologies and the results showed that Cu was incorporated into the perovskites lattice successfully. In addition, the introduction of Cu resulted in the mixed valence state of Fe(III)/Fe(II) and Cu(II)/Cu(I) in perovskite structure.

Photocatalytic removal of tetrabromobisphenol A by magnetically separable flower-like BiOBr/BiOI/FeO hybrid nanocomposites under visible-light irradiation.

A novel flower-like three-dimensional BiOBr/BiOI/FeO heterojunction photocatalyst was synthesized using a simple in situ co-precipitation method at room temperature. The hybrid composites were characterized by a couple of techniques including X-ray powder diffraction, scanning electron microscope, transmission electron microscopy, ultraviolet-visible diffuse reflection spectroscopy, Brunauer-Emmett-Teller, X-ray photo-electron spectroscopy, photoluminescence technique, and vibrating sample magnetometer. FeO nanoparticles were perfectly loaded on the surface of BiOBr/BiOI microspheres.
