Wastes and by-products of agricultural industry are huge in amount and difficult to handle. These predominant waste materials could be utilised by converting them into a useful products such as biosorbents. The effluent holding the toxic cationic dyes from textile industry is a threatening factor now days due to environmental legalizations and their adverse effect on human biota. Under this circumstance the cheap form of the effective adsorbents from the agricultural waste for the removal of such kind of dyes can be considered. This paper reviews on the agricultural waste products for the removal of cationic dyes from the textile industry effluent and also briefly discusses about the model equations used for adsorption isotherms and kinetics.
