Somenath Mitra, distinguished professor of chemistry and environmental science, was awarded a patent last month for a next-generation water desalination and purification technology that uses uniquely absorbent carbon nanotubes to remove salt and pollutants from brackish water and industrial effluent for reuse by businesses and households.
Mitra’s new carbon nanotube immobilized membrane (CNIM) is an energy-efficient device designed to filter higher concentrations of salt than is currently feasible through reverse osmosis, one of the standard industry processes. It is also used to remove pollutants such as volatile organic compounds (VOCs) – chemicals routinely used in solvents – from water.
