Presence of dyes in the aquatic systems has become a serious environmental problem. Based on this idea, focusing the environmental issue and economic point of view, the use of low cost and eco-friendly bioadsorbents were investigated for removing the textile dyes from wastewater. Bioadsorbents with a surface area of 336.224 and 21.456 m2/g were prepared from orange and banana peels, respectively. The surface area of activated orange peel was large due to its surface area largely expanded when HCl apply on the sample. In both samples the presence of alkyl, carboxylic acids, ketone, aromatic compounds, alkene and alkane were confirmed by FTIR Spectrometer analysis. The experimental design used for the experiments was a general full factorial design which was designed by Design Expert Software. Batch adsorption experiments were performed for the adsorption of the reactive red dye molecule from aqueous solution over both bioadsorbents. The effects of pH, bioadsorbents dosage, temperature, contact time and initial dye concentration were studied on percentage of RRD removal from aqueous solution. The UV spectrometry technique was used for measuring of absorbance values in dye solution before and after adsorption experiment. A maximum removal of 89.41 and 70.25% were obtained at pH of 4, initial dye concentration of 25mg/L and temperature of 30 onto activated orange and banana peels adsorbent, respectively. The experimental results have been fitted well by both Langmuir and Freundlich isotherm model for both over activated orange and banana peels adsorbent. Moreover, adsorption kinetics were determined using pseudo first order and pseudo second order models and it was found that the adsorption process follows the pseudo second order model for both over activated orange and banana peels adsorbent.
