Many researchers1-3 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.

Characterization of Palm Nut Shell Carbon and Treated Flyash Residue for Adsorption of Coloring Matter from Aqueous Systems

The Palm Nut Shell Carbon (PNSC) and Treated Flyash Residue (TFR) has prepared by sulphuric acid process and characterized. The characterization studies includes determination of moisture, bulk density, pH, carbon soluble in water and acid, decolourising power, iron content, phenol number and surface area parameters. The characteristics of these carbons were compared with that of high cost activated charcoal carbon (ACC). The PNSC and TFR were used for adsorption of colouring matter from the textile dyeing industrial effluents.
