Abstract
Brine sludge is an industrial waste generated in chloral alkali industry. The generated brine sludge waste is dumped into landfills and contains barium sulphate, calcium carbonate, magnesium hydroxide, sodium chloride, clay, and toxic elements like chromium, zinc, copper, and vanadium, therefore posing an environmental threat. Consequently, there is an urgent need to convert toxic brine sludge waste into its non-toxic form. The present invention thus aims to achieve total utilization of this brine sludge for making functionalized brine sludge material useful for a broad application spectrum.
