Degradation of thiamphenicol by La-FeO/DBD/HCP synergistic catalytic system.

In this study, a highly efficient La-FeO/dielectric barrier discharge (DBD)/honeycomb ceramic plate synergistic catalytic system was successfully constructed by using modified iron oxide (FeO) catalyst coating assisted DBD plasma, and the prepared catalytic coating was fully characterized by various techniques. The results indicate that the lanthanum (La) is efficiently and uniformly doped in FeO, and the modified La-FeO catalyst exhibited a better photocatalytic performance. The overuse of Thiamphenicol (TAP), as a typical chloramphenicol antibiotic, has led to its accumulation in the aquatic environment.

A thorough investigation into the adsorption behavior of sophorolipid-modified fly ash towards compound pollution of lead and tetracycline.

Heavy metal ions and antibiotics were simultaneously detected in authentic water systems. This research, for the first time, employed synthesized sophorolipid-modified fly ash(SFA) to eliminate tetracycline(TC) and lead(Pb) from wastewater. Various characterization techniques, including SEM-EDS, FTIR, XPS, BET, and Zeta, were employed to investigate the properties of the SFA.

Material flow analysis of heavy metals in large-scale cattle farms and ecological risk assessment of cattle manure application to fields.

This study bridges the knowledge gap pertaining to the pathways of heavy metal accumulation and migration within the industrial chain of large-scale cattle farms. Two such farms in Shaanxi serve as a basis for our exploration into Zn, Cu, Cr, Pb, As, and Cd dynamics. Employing material flow analysis complemented by predictive models, we evaluate the potential ecological risks of arable soil from heavy metal influx via manure application.

Enhancing the carbon content of coal gangue for composting through sludge amendment: A feasibility study.

Cocomposting coal gangue and sludge eliminates the challenge of utilizing coal gangue. However, there is limited understanding about the feasibility of cocomposting sludge and coal gangue, as well as the composting indicators, functional microorganisms, and safety risks involved. Therefore, this study evaluated the feasibility of enhancing carbon composting in coal gangue by incorporating sludge along with sawdust as a conditioner.

Synergistic catalysis induced by a multi-component system constructed by DBD plasma combined with α-FeO/FeVO/HCP and peroxymonosulfate for gatifloxacin removal.

The dielectric barrier discharge (DBD) multi-component system containing plasma, α-FeO/FeVO, and peroxymonosulfate (PMS) with high catalytic activity was successfully constructed. Thereinto, α-FeO/FeVO was loaded on the honeycomb ceramic plate (HCP) surface (α-FeO/FeVO/HCP) and placed under the water surface below the discharge area. The catalytic activity was evaluated by the removal rate of gatifloxacin (GAT), and the DBD+α-FeO/FeVO+PMS system exhibited the optimal catalytic activity.

Fabrication and Separation of EGaIn Microparticles from Human Blood Based on Dielectrophoresis Force and a W-Type Electrode.

Harmful particles such as heavy metal particles in the human body can cause many problems such as kidney stones, gallstones, and cerebrovascular diseases. Therefore, it is critical to separate them from the blood and perform a systematic analysis as early as possible. Here, we apply eutectic gallium indium (EGaIn) microparticles as a model to study the separation of particles from blood, thanks to their properties of low toxicity, excellent degradability, and negligible vapor pressure.

Abundance and characteristics of microplastics in the surface water and sediment of parks in Xi'an city, Northwest China.

Microplastics (MPs), as a new type of pollutants, have attracted wide attention especially in recent years, but there was insufficient research on the distribution and characteristics of MPs in urban park water body. In this study, the pollution of MPs in water and sediment of Xi'an, the largest city in northwest China, was investigated. The MPs concentration in the surface water and sediment was 2900-6970 items/m and 940-3560 items/kg, respectively.
