Activated carbon was prepared from Rubber Wood, an illimitable indigenous source obtained from Kerala by chemical activation using phosphoric acid as all activating reagent. The carbon was prepared by changing the parameters like activation time, particle size and concentration of the impregnating reagent. The parameters were changed in order to prepare the good quality carbon. The prepared carbon was characterised by its Iodine and Methylene Blue Number. The obtained Iodine and Methylene Blue Number illustrates that the carbon obtained is in the meso-macropore range and its suitability in liquid phase applications. The optimised carbon was used for the removal of Remazol Red (5B) dye. The parameters like contact time, pH, and carbon dosage were studied in order to study the influence of these parameters during adsorption. Adsorption isotherms were studied by varying the particle sizes and was analysed by Langmuir and Freundlich models. Adsorption studies show favourable adsorption and was found that resulting carbon is well suitable for removal of colour from effluents.
