Leveraging Industrial Jarosite Waste for Arsenic(V) and Chromium(III) Adsorption from Water: A Preliminary Study

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(3), P. 1469 - 1469

Published: Jan. 31, 2025

The global problem of water scarcity is exacerbated by the continued contamination potable sources. This preliminary study investigates potential a hazardous industrial jarosite waste to adsorb As(V) and Cr(III) from contaminated waters. results showed that this mining effectively adsorbed both Cr(III), demonstrating its as low-cost sustainable solution for remediation along with use also contaminates. adsorption process was optimized, effects various parameters on capacity were investigated. findings suggest toxic residues in porous concrete could provide promising approach removal heavy metals polluted sources, contributing development more environmentally friendly treatment technologies. A maximum 90.6% 96.3% achieved, it verified initially contained about 0.44% As, which later leached during decomposition; again, able re-adsorb Cr(III).

Microbially Mediated Arsenic-Nitrogen Biogeochemical Coupling Across Vertical Distribution in Coastal Wetlands

Water, Journal Year: 2025, Volume and Issue: 17(9), P. 1255 - 1255

Few studies have addressed the coupling of arsenic (As) and nitrogen (N) geochemistry in natural soil. This research focused on vertical distribution behavior As N coastal wetland sediments. Pore water sediment from barren wetlands near three estuaries (Guanhe River, Sheyang Liangduo River) central Jiangsu Province China with Spartina alterniflora (S. alterniflora) were sampled, which analyzed for total content speciation inorganic fractions. The bacterial community was investigated through 16s rDNA sequencing; diversity indices calculated. change trend pore surface increasing depth opposite to that NO3−, possibly because NO3− promoted arsenite (As(III)) oxidation arsenate (As(V)). Increased contents seemed mitigate toxicity. NH4+ indicated anaerobic ammonium iron (Fe) reduce Fe oxides, resulting release, especially deeper sediment. High-throughput sequencing analysis revealed some potential bacteria involved As-N geochemical coupling, such as Bacillus Psychrobacter, can couple denitrification oxidation, Sva1033, may favor oxidation-induced release. Our results suggest N-driven As(III) release be relevant processes emphasize importance microorganisms processes. deepens our understanding wetlands, providing a theoretical basis controlling pollution.
