Abstract:
In this research a new efficient adsorbent of dyes is used. Thus, adsorption of some textile dyes from aqueous solution by using an industrial waste lignocellulosic product is studied. Between five dyes tested, three dyes were chosen for testing: Direct Orange 26, Acid Orange 7, Acid Green 20. Kinetics of adsorption and equilibrium isotherm of dyes was investigated using Longmuir and Freundlich models. This study showed that the beech wood sawdust could be employed as low-cost and effective sorbent for the removal of dyes from aqueous solution.
