CuMn2O4/chitosan micro/nanocomposite: Green synthesis, methylene blue removal, and study of kinetic adsorption, adsorption isotherm experiments, mechanism and adsorbent capacity

Malihe Samadi Kazemi et al.

Summary: In this study, a pure phase of CuMn2O4 nanostructures were fabricated using a simple and environmentally friendly hydrothermal method with onion as a capping agent.

Mechanism of arsenic immobilization and biotransformation in the biological aqua crust of mine drainage

Chiyu Chen et al.

Summary: This study examined the mechanisms of As immobilization and biotransformation in Biological Aqua Crusts (BACs). The results showed that BACs could immobilize As through bioadsorption/absorption and biomineralization processes driven by Cyanobacteria. The high abundance of As(III) oxidation genes enhanced microbial As(III) oxidation, resulting in the conversion of As(V) into a less toxic form. The findings highlight the important role of BACs in As remediation in mine drainage.
