❖ Researchers at the Indian Institute of Science (IISc) have developed a nano material-based solution to address heavy metal contamination in water.

❖ The team has developed an innovative nanomaterial that could help clean up chromium-contaminated groundwater.

❖ The material is called ‘sulphidated' carboxymethyl cellulose-stabilised nanoscale zero-valent iron (S-CMC-nZVI).

❖ It has shown remarkable efficiency in removing hexavalent chromium, a toxic form of the metal, from water.
