Title: Adsorptive removal of Reactive and Direct dyes using non-conventional adsorbent – Column studies
Authors: Sivakumar, P

Abstract: This study presents effect of influent concentration, flow rate and bed height on packed bed column prepared by Euphorbia antiquorum L activated carbon used for adsorptive removal of dyes, Reactive Red 4 and Direct Blue 53. Adsorption efficiency increases with increase in influent concentration and bed depth and decreases with increase in flow rate. Yoon-Nelson model described adsorption behaviour of selected adsorbent-adsorbate system more reasonably than Thomas model and Reactive Red 4 adsorption behaviour fits exceptionally well with Yoon-Nelson model.
