E-email: msalam@mnnit.ac.in Manuscript received online 29 October 2020, revised and accepted 31 October 2020 Column studies with iron impregnated coconut husk (IICH) were carried out to demonstrate its potential and for practical suitability as an adsorbent for treatment of water containing arsenic (III) i.e. As(III) at industrial scale. The required experimentations were performed and using the data generated, the breakthrough curves were prepared depicting the adsorption of As (III) on IICH at different concentration (10-100 mg/l), different bed depth (10-30 cm) and different flow rate (1-4 ml/l) with the constant initial pH of influent solution 7.5. On analyzing the data, the breakthrough time was observed to decrease with increase in initial As (III) concentration and flow rate but it increases with an increase in bed height. The higher value of bed height is not recommended. The experimental data obtained during this work were fitted with Thomas model at different experimental conditions of inlet concentration, bed height and flow rate. The experimental breakthrough curves were close to the predicted by Thomas model.
