Globally wastewater from textile industry becomes a serious health, safety and environmental issue. Dye containing wastewater is toxic in nature alter the physicochemical characteristics of receiving bodies. In term of cost effective and performance only few methodology are available. On this inspiration low cost and eco-friendly bioadsorbents from agricultural waste were investigated to treat dye contains wastewater. The aim of investigation is to remove the reactive red dye (RRD) from textile industry wastewater by activated orange and banana peel. The textural characterization shows 336.224 m2/g and 21.456 m2/g (specific surface area) for orange and banana peels respectively. The experiment conducted in batch mode to optimize the maximum operating condition. The result shows maximum removal efficiency of 89.41% and 70.25% at pH of 4, initial dye concentration of 25 mg/L, adsorbent dosage 1 g/100 mL, and temperature of 30 °C on the activate surface of orange and banana peels. The obtained results were well fitted with Langmuir and Freundlich isotherm model and adsorption process follows the pseudo second order model for both adsorbent. Overall both peels have good potential to reduce the dye from wastewater.
