Chromium (III) Removal from Synthetic Tannery Wastewater Using Chlorella vulgaris Biomass as a Sustainable Biosorbent: Kinetics, Isotherms and Mechanistic Insights
Chromium-bearing effluents from the tanning industry pose significant environmental concerns owing to high metal loading and ecological risks. Cr(III) can accumulate in aquatic systems and may oxidize to more hazardous species under certain conditions. This study investigated Cr(III) removal from synthetic tanning wast...
