Summary: A novel Fenton-like catalyst was synthesized by incorporating Fe2O3 nanoparticles on the surface of nanocellulose derived from sugar beet pulp. The catalyst exhibited high efficiency in removing three different dyes. The SBP-based nanocatalyst (Fe/NC-S3) showed the best results due to its larger surface area and higher content of magnetic nanoparticles. The Fe/NC-S3 nanocatalyst demonstrated proper reusability and practical application in dye removal from complex matrixes.

Summary: This study enhances the catalytic efficiency of pyrite by pre-reaction with hydrogen peroxide to degrade recalcitrant contaminants. By optimizing factors such as pre-reaction time, hydrogen peroxide concentration, solution pH, and dye concentration, efficient degradation of contaminants using natural pyrite was achieved. Enhanced dye degradation was attributed to the production of hydroxyl radicals facilitated by self-regulation of pH, Fe2+ release, and Fe2+/Fe3+ cycle.

Summary: The study focused on treating wastewater from rayon fiber production. Mass balance and repeated analysis were conducted on three sources of problematic process wastewater. The high COD (0.4-30 g/L), TOC (0.09-7.1 g/L), and Zn2+ (0.09-0.5 g/L) concentrations in all three sources pose a significant pollution threat to the Elbe River (with a total volume of 1.84 million m3). Lab-scale tests were done using filtration, microfiltration, and oxidation methods, along with the adsorption of Zn2+ emissions using cation exchange resin. The optimized technological sequence achieved up to 98% COD reduction and 85% TOC reduction, while also converting Zn2+ emissions into reusable zinc sulfate during the cation regeneration process.

Summary: The study found that Cr(VI) was quickly adsorbed onto the magnetite surface and directly reduced to Cr(III) by the active Fe(II) on the surface. However, the reduction rate gradually decreased over time, possibly due to the formation of a maghemite passive layer on the outer-sphere of magnetite.

Summary: This study investigated the impact of particle size distribution and clay minerals on ammonia nitrogen pollution caused by weathered crust elution-deposited rare earth tailings. The results indicated that as soil particle size decreases, both soil specific surface area and clay content increase, leading to stronger AN enrichment ability. Clay minerals with different capacities for AN enrichment vary with sampling depth, influencing the distribution of AN in the mine site where a pattern of increase and then decrease in AN content with vertical depth was observed.

Summary: The study investigated the characteristics and mechanisms of different fractions of lead released by various leaching agents in the process of eliminating ammonia nitrogen pollution in rare earth ore mining. The results showed that Al-2(SO4)(3) released the highest amount of lead, followed by (NH4)2SO4 and MgSO4, with both acid extractable and reducible fractions being released. pH had little effect on the release of lead by (NH4)2SO4 and MgSO4 in leaching the ore, while the residual acid extractable fraction of lead was highest after water injection using Al-2(SO4)(3).

Summary: The study investigates the use of bamboo charcoal modified by potassium permanganate and sodium silicate (KSBC) as an adsorbent for ammonia nitrogen (AN) pollution caused by weathered crust elution-deposited rare earth ore (WCED-REO) mining in Jiangxi province. The results demonstrate that KSBC has a rich microporous structure and abundant functional groups, leading to a maximum adsorption capacity for NH4+-N that is four times larger than that of bamboo charcoal (BC). Interference experiments also show that KSBC performs well in the presence of some interferents. Density functional theory (DFT) calculations further explain the reduced participation of interferents. The adsorption mechanism involves electrostatic interaction, surface complexation, and ion exchange interaction. Desorption experiments reveal a good regeneration potential with electrostatic interaction and ion exchange contributing to 86.29% of the adsorption efficiency. These findings provide theoretical support and guidance for the development and application of BC-based biochar adsorption material in the treatment of nitrogen-contaminated water in WCED-REO areas.

Summary: In this study, we developed a laser-induced graphene (LIG) electrode modified by gold nanoparticles (AuNPs) and glycine-modified nanocarbon (Gly-C) for the detection of nitrite. The electrode's physical and electrochemical characteristics were analyzed using various techniques. The results showed that the addition of AuNPs enhanced the electrocatalytic oxidation of nitrite, while Gly-C improved the hydrophilicity and nitrite adsorption capacity of the electrode surface. The developed sensor exhibited a linear range of 7-700 μg/L and 700-1050 μg/L, with a detection limit of 0.84 μg/L. The sensor demonstrated excellent anti-interference, repeatability, and stability, with recovery rates ranging from 94% to 123% in actual groundwater and tap water samples. The relative standard deviation was less than 6.06%. This study provides a potentially effective method for on-site monitoring of nitrite in aquatic environments.
