The last decade has witnessed the influx of significant research output in the area of green sorbents for water and wastewater treatment. These sorbents, which are derived from environmentally friendly, renewable, and locally available sources, such as lignocellulosic materials and biomass, have shown promising results in removing organic dyes, heavy metals, and micropollutants. With recent repor…

IntroductionSelective absorption of pollutants can be attained using smart nanomaterials despite the fact that most of the conventional methods of treating water separate the sensing process from the actual remediation. This work proposes a new approach where smart nanomaterials are used in sensing water quality using artificial intelligence in a closed-loop system while estimating adsorption cap…

Iron sulfides represent a reactive class of materials, and their structural diversity, phases and redox-active surfaces have a strong bearing on environmental processes. Iron-sulfide minerals occur widely in anoxic sediments and aquatic systems, where they take part in a range of biogeochemical reactions. Yet iron-sulfur chemistry is not confined to the mineral phases alone. Nanoparticulate FeS e…

IntroductionLead (Pb2+) contamination in acid mine drainage (AMD) poses a significant environmental challenge due to its persistence, bioaccumulation potential, and severe toxicity to living organisms. This study evaluated the performance of a Fenton-modified pine cone-derived poly (hydroxamic acid) (PHA) ligand for the selective removal and recovery of Pb2+ from acidic mine drainage systems.Meth…

IntroductionWildfires can substantially alter soil geochemistry in fire-prone environments, yet their influence on inorganic nanoparticles (NPs) remains poorly constrained.MethodsThis study investigated nanoparticle dynamics following a wildfire in the Cantillana Reserve (central Chile) by combining field sampling, controlled combustion experiments, bulk geochemical analyses, and single-particle …
