Many researchers aimed to study the removal of colouring matter from textile dyeing industrial effluent using the carbon derived from natural sources. Because adsorption of the dyes on carbon is easily, cost effective when comparing to the other techniques. Hence we aimed at the preparation and characterization of the carbon from the natural sources like palm nut shell and flyash. These carbons have been used for adsorption of direct dye Black E. The effect of pH, carbon dose and equilibration period were examined along within the Langmuir and Freundlich isotherm studies. The application of these carbons was investigated on adsorption and colour removal from effluent and synthetic samples, which consists of commercial direct dye Black E.
