Indian researchers develop nanomaterial that helps in the treatment of wastewater without using any chemical



Membrane-based filtration processes are generally used to treat industrial wastewater but they can’t fully filter out heavy metal contaminants. In order to address this problem, processes that use activated carbon, graphene or carbon nano tubes are being developed as carbon-based processes can help remove dyes and heavy metals through adsorption.

Researchers at the Central Salt and Marine Chemicals Research Institute, Bhavnagar, have gone a step further to make carbon-based cleaning process fully green by using seaweed as starting material. They have synthesised Graphene-Iron sulfide nanocomposite from abundantly found seaweed — Ulva fasciata – through direct pyrolysis technique.
