Removal of Acid Orange 3 from Aqueous Solution by Activated Carbon Adsorption
Asian Journal of Chemistry,
Vol. 22 No. 1 (2010): Vol 22 Issue 1, 2010
Abstract
Removal of acid orange 3 from aqueous solution by activated carbon
adsorption was studied. The optimal adsorption conditions for the removal
of acid orange 3 aqueous solution were pH = 0.5, activated carbon 500
mg L-1, initial concentrations of the dye 100 mg L-1 and T = 35 ºC, a
removal efficiency of 98 % was achieved within 1 h. Kinetic data of
adsorption were well fitted the pseudo-second-order kinetic model and
the Langmuir isotherm. The approach may be applied to treat the industrial
wastewater containing acid orange 3 if appropriate conditions are
selected.
