Bhubaneswar: Researchers at the National Institute of Technology, Rourkela have developed a low-cost ceramic adsorbent using industrial by-products that can remove more than 95% of a commonly used dye from industrial waste water.
The team used fly ash from thermal power plants, ground granulated blast-furnace slag from the steel industry, and kaolin clay to create the adsorbent capable of removing methylene blue dye from contaminated water.
The study was led by Prof Sunipa Bhattacharyya, associate professor in the department, along with research scholars Susant Mohapatra and Sourav Ranjan Satpathy.
This innovative approach not only addresses wastewater pollution but also provides a sustainable use for industrial waste materials. The adsorbent's high efficiency in dye removal makes it a promising solution for textile and other industries that discharge colored effluents.
