Adsorptive capacity of five different low cost adsorbents (Baggase pith, orange peel, Saw dust, Eichhornia roots and shoot)has been tested for the decolourization of waste water containing methylene blue. The adsorption capacity of each adsorbent has been determined and this adsorption capacity was compared with activated carbon. The process of adsorption is brought about at ordinary conditions of room environment. The various adsorption precesses investigated are the effect of pH, effect of initial dye concentration and different adsorbent doses. Removal of the dye was found to increase with decrease in initial dye concentration, increase in adsorbent dose and pH. Removal to the extent of 95-100 per cent was observed in low dye concentration and high adsorbent dose and pH. Eichhornia plant is found to be a best adsorbent than other materials studied for the purpose.
