| dc.description.abstract | In this study, it was investigated batch adsorption of Reactive Blue 221 which is a textile dye with pumice stone. pH, shaking time, shaking rate, adsorbent particle size and amount were selected as constant parameters but solution temperatures and dye concentrations were selected as variables. Adsorption capacities were determined as 36.60 mg/g ve 47.90 mg/g ve 54.20 mg/g for pumice stone at 293 K, 318 K and 333 K temperatures respectively, in the 7.0 pH, 0.59 mm particle size, 2.00 g adsorbent amount and approximately 1.5 hours shaking time for 8×10-4 M dye concentration. Adsorption data were good agreement with Langmuir isotherm and adsorption was an endothermic and spontaneous process in the results of thermodynamic parameters. The kinetic data of the sorption showed that the pseudo second- order equation was the more appropriate and it was not only obtained an economic process with using of environmentally friendly, easily finded and low cost adsorbent and but also high color removal was obtained in dye. | |
