An innovative nanomaterial called ‘sulphidated’ carboxymethyl cellulose-stabilised nanoscale zero-valent iron (S-CMC-nZVI) has been developed to address heavy metal contamination in water by the Indian Institute of Science (IISc) in Bengaluru.
The solution is efficient in removing hexavalent chromium metal from water while addressing contamination of Bellandur lake as well as groundwater. It can also be helpful in treating other contaminants like cadmium and nickel in the lake.
