Researchers from Korea’s University of Seoul, Russia’s RUDN University and several India-based institutes have created a nano-filter for water purification from synthetic dyes. The graphene-based composite can reportedly remove up to 100% of harmful compounds from water, and it can be used up to seven times without losing efficiency. In addition, the synthesis of the nanofilter itself is economical and environmentally friendly.
Synthetic dyes are used in industrial chemistry and pharmaceuticals. They reach the wastewater together with other industrial waste and pollute the environment. Existing methods of water purification are not quite practical, as the proposed adsorbents are usually disposable and work slowly. Therefore, scientists continue to look for effective and eco-friendly solutions to this problem. The team in this recent work has proposed a reusable graphene-based nanocomposite that can quickly absorb dyes from water.
