Acid activated carbon obtained from cheap, non-toxic and locally available banana peel was used as alow cost and efficient adsorbent for the removal of dyes methyl orange and rhodamine-B from theaqueous solution. Changes in the resulting material before and after activation and after treatmentwere studied by different techniques, such as SEM-EDX, XRD, FTIR measurements. Effects of durationof treatment, amount of banana peel activated carbon, pH, and initial methyl orange and rhodamine-Bconcentration, on the removal of dye were studied to get optimum conditions for maximum dye removal.Removal efficiency of the activated ash remains almost constant in a wide range of pH from 2.5 to 5.6.In 75 min at room temperature removal of 98.5 % methyl orange (anionic) and 99.0 % rhodamine-B(cationic) dyes with 0.1 g and 0.125 g, respectively was obtained from the contaminated water having10 ppm dye concentration.
