Abstract
Dyes from industrial and laboratory waste are major water pollutants. Most of the dyes are stable to degradation. In this, the removal of Rhodamine-B from its aqueous solutions by adsorption on different plant leaf powder such as Annona squamosa, Manilkara zapota and Prosopis julifora were studied. The effects of various experimental parameters on adsorption such as pH, dye concentration and sorbent dosage were examined and the optimal experimental conditions were evaluated. The maximum removal of color was achieved by Annona squamosa with dosage of 1gm/100ml of effluent at neutral pH. In acidic pH (5.6) Manilkara zapota reduced more color (68.33%).
