Abstract :Activated biomass charcoal produced from peanut shells was utilized as an adsorbent for the removal of basic red 2 insert ignore into journalissuearticles values(BR2); dye from aqueous solution in batch and column systems. In batch system, the effects of shaking time, initial BR2 concentration, solution pH and temperature on the adsorption were studied. While the adsorption was increasing with increasing contact time, initial BR2 concentration and temperature, it decreased with increasing solution pH. In column system, the effects of solution flow rate and initial BR2 concentration were investigated. The adsorption of BR2 was determined between 82.40 and 99.91% u nder all conditions such as concentration, temperature and pH for batch system. The column adsorption was found as 99.50%. Adsorption obeyed the Freundlich isotherm and and the pseudo-second order kinetic model. SEM and FT-IR studies indicated that a surface adsorption might probably be occurred on the heterogeneous surface of activated biomass charcoal .
