- Indian Institute of Technology Guwahati (IITG) researchers developed a biological material using cyanobacteria (blue-green algae) to remove lead from contaminated water.
- The research team led by Professor Debasish Das from the Department of Biosciences and Bioengineering found that exopolysaccharides (EPS), a sugar-rich substance produced by algae, can absorb toxic lead particles.
- The developed biological material removed 66.2% of lead from polluted water by binding with lead particles through natural chemical groups.
- Cyanobacteria are naturally available in ponds, lakes, reservoirs, paddy fields and slow-moving freshwater bodies, making the method sustainable and eco-friendly.
- Conventional methods like chemical precipitation, membrane filtration and ion exchange are costly and generate secondary pollutants, while this method offers a greener alternative.
