Abstract
The prepared PANi/MnO2 is an efficient adsorbent to remove congored from aqueous solution. It decolorize as much as 84 % of the dye from an aqueous solution (40 mg/L) at 30oC if agitated for an hour. The experimental data yielded perfect fit with Langmuir The enthalpy change for the adsorption process was in the range of 36 to 54 kJ mol-1, which indicate very strong chemical force between the adsorbed dye molecules and the polymer surface. Hence, physisorption seems to be the major mode of adsorption.
