Vetiver biochar application for heavy metal sequestration in water treatment: bridging perfumery waste and environmental sustainability

Converting industrial byproducts into functional adsorbents supports circular and sustainable approaches to water treatment. This study evaluated biochar derived from spent vetiver ( Chrysopogon zizanioides ) roots, a byproduct of the perfumery essential-oil industry, for the competitive adsorption of copper (Cu),...
