摘要

This review highlights the potential of nanoparticle (NP)-based biosorbents, known as nanobiosorbents (NBS), for removing hazardous uranium, particularly U(VI), from wastewater systems. It also explores the use of green-synthesized NPs for wastewater treatment. Nuclear power generation and mining release large amounts of U(VI) into wastewater. The chemical toxicity of U(VI) poses a threat to ecosystems. NBS have been applied at industrial scales. They reduce internal diffusion resistance and increase binding capacity. This enhances biosorption efficiency. Chemical synthesis of NPs has drawbacks. Thus, researchers now use plant biomass and microbes for eco-friendly NP synthesis without chemicals. Recent studies showed advances in green NBS, such as bacterial-mediated TiO2/ZnO composites. These offer high capacities and reusability.
