Purification of industrial waste water polluted by anionic dye was carried by adsorption process. Anionic dye (i.e. Acid Yellow 24) from waste water can be effectively taken out by Madhuca Longifolia Seeds Hull (MLSH) as adsorbent in the sorption technique. MLSH is a low cost and easily available agricultural waste in our ambience. Batch equilibrium method was followed to study the effects of some physico-chemical experimental conditions such as pH, agitation time and adsorbent dose. Equilibrium adsorption isotherm was also studied and found to be suitable with Freundlich isotherm. Kinetic parameters were in conformity with pseudo-second order. The present research projects towards applicability of MLSH in designing low cost adsorbent and for treating effluent water in industries or other adsorption processes. The observations and findings were interpreted at laboratory scale.
