This study assessed the suitability of Dextrin White, a biopolymer, as an adsorbent to remove chromium (VI) from water. Experiments were conducted in batch mode by changing factors such as contact time, adsorbent amount, and initial chromium concentration. Under conditions of 1 g adsorbent, 2 hours of contact time, and an initial concentration of 50 mg/l, maximum removal reached 91% with a loading capacity of 2.25 mg per gram. FTIR analysis confirmed the binding of chromium to Dextrin White. The experimental data were analyzed using Freundlich and Langmuir isotherm models, with the Langmuir model providing a better fit—indicating monolayer adsorption on the adsorbent surface. The findings suggest that Dextrin White holds strong potential for effective treatment of chromium(VI) in tannery wastewater, which is particularly relevant for industrial effluent management in the Indian context.
