Currently, large-scale burning is an important straw disposal method in most developing countries. To execute prescribed while mitigating air pollution, it crucial to explore the maximum possible range of meteorological changes. This study conducted a three-year monitoring program Changchun, core agricultural area Northeast China severely affected by burning. The data included ground-level pollutant monitoring, ground-based polarized LiDAR observations, and ground factors such as planetary boundary layer height (PBLH), relative humidity (RH), wind speed (WS). Using response surface methodology (RSM), this analyzed key weather parameters predict optimal for emission reduction effects. results revealed that PM2.5 was primary during period, particularly lower atmosphere from March April, with rising sharply April due exponential increase fire points. Furthermore, phase, average WS PBLH increased, whereas RH decreased. Univariate analysis confirmed these three significantly impacted concentration. RSM relevance prediction model (MET-PM2.5) established correlation equation between levels identified combination indices: (3.00–5.03 m/s), (30.00–38.30%), (0.90–1.45 km). Notably, (33.1%) emerged significant influencing factor, value remained below 75 μg/m3 when all indicators varied less than 20%. In conclusion, findings could provide valuable screening schemes improve planned residue policies, aim minimizing pollution activities.

New Antifouling Dual Iron-Based Photo-Fenton Catalytic Membrane Dedicated to Long-Term Treatment of Oils and Dyes

Nano Letters, Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

Combining the photo-Fenton catalytic reaction with membrane separation technology can effectively treat oils and dyes in water. However, single iron-based catalysts suffer from limited photogenerated carrier utilization slow Fe3+/Fe2+ redox reactions, leading to contamination. In this study, iron oxyhydroxide Prussian blue were grown on a PVDF membrane, optimizing electron transfer improve efficiency (the methylene degradation was nearly 50% 10 min rate constant 0.094 min-1). The flux for multicomponent oily wastewater reached 965.3 L·m-2 h-1, an over 99.9% dye removal rate. of actual printing dyeing after continuous filtration 60 373.6 h-1. Moreover, mechanisms explained detail. strategy provided study has certain practical application value treatment.
