Abstract

The adsorption of dyes from aqueous solution has been investigated on Orange Peels (OP). The influence of pH, contact time, adsorbent dosage, dye concentration, agitation speed, temperature and particle size of biosorbent on the biosorption has been investigated. The biosorptive capacities of the biosorbents were dependent on the pH of the dye solution, with pH 2 and 4 being optimal. From the analysis of isotherm data obtained from the fittings of the Freundlich model fits better than the Langmuir model in case of acid blue MTR dye and in case of red 3BLS disperse dye Langmuir model fits better than Freundlich model. The adsorption capacities were found to be 19.48, 36.67, 16.69mg/g for FOP, IOP, DOP in case of Acid Blue MTR Dye and similarly 23.35, 29.36, 27.30mg/g respectively in the case of Red 3BLS Disperse Dye.
