Large-Scale Nanofiber Manufacturing| An ionic liquid-modified PVC nanofiberfacilitates gold recovery from wastewater bya light-enhancing effect 2025-05-08
With rapid industrial development, gold as a precious metal has been widely used in various industrial fields. However, wastewater from metallurgical industries contains gold, and direct discharge causes resource waste and economic losses. While novel adsorbents like MOFs, COFs and functionalized polymers demonstrate satisfactory gold adsorption capabilities, they face limitations including complex synthesis, high costs, poor acid/alkali resistance, and difficult recycling. In contrast, electrospun nanofibers offer simpler preparation, cost-effectiveness, and easier recyclability. Their unique long fibrous morphology provides extensive grafting areas for functional adsorption sites, ensuring effectiveness and feasibility. Therefore, developing functional electrospun nanofibers for efficient gold recovery from wastewater is crucial for precious metal recycling.
