Silver ions in wastewater streams are a major pollutant and threat to human health. Given the increasing demand relative scarcity of silver, these could be lucrative source extract metallic silver. Wastewater is complex mixture many different metal salts, developing recyclable sorbents with high specificity towards silver remains challenge. Here we report that molybdenum oxide (MoOx) adsorbent mixed-valence (Mo(V) Mo(VI)) demonstrates selectivity (distribution coefficient 6437.40 mL g-1) for Ag+ an uptake capacity 2605.91 mg g-1. Our experimental results density functional theory calculations illustrate mechanism behind adsorption reduction. show Mo(V) species reduce Ag, which decreases energy barrier subsequent reductions, accounting from wastewater. Due its selectivity, MoOx favorably adsorbs even presence interfering ions. High selective recovery (recovery efficiency = 97.9%) further supports practical applications sorbent. Finally, can recycled following while maintaining 97.1% after five cycles. The method expected provide viable strategy recover

Removal of contaminants in wastewater, such as heavy metals, has become a severe problem the world. Numerous technologies have been developed to deal with this problem. As an emerging technology, nanotechnology gaining increasing interest and many nanomaterials remove metals from polluted water, due their excellent features resulting nanometer effect. In work, novel nanomaterials, including carbon-based zero-valent metal, metal-oxide based nanocomposites, applications for removal metal ions wastewater were systematically reviewed. Their efficiency, limitations, advantages compared discussed. Furthermore, promising perspective environmental was also discussed potential directions future work suggested.

Covalent organic frameworks (COFs) are a new type of crystalline porous polymers known for chemical stability, excellent structural regularity, robust framework, and inherent porosity, making them promising materials capturing various types pollutants from aqueous solutions. This review thoroughly presents the recent progress advances COFs COF-based as superior adsorbents efficient removal toxic heavy metal ions, radionuclides, pollutants. Information about interaction mechanisms between summarized macroscopic microscopic standpoints, including batch experiments, theoretical calculations, advanced spectroscopy analysis. The adsorption properties assessed compared with other widely used adsorbents. Several commonly strategies to enhance materials' performance relationship property sorption ability also discussed. Finally, summary perspective on opportunities challenges proposed provide some inspiring information designing fabricating environmental pollution management.
