Publisher: | SPRINGER HEIDELBERG | Abstract: | This study was performed to evaluate Cr(VI) removal performance of three anion-exchange resins with different quaternary amine functional groups by varying the conditions of the solution phase. The effects of process variables on the sorption, such as solution pH, temperature, adsorbent dose, phases contact time, and initial Cr(VI), concentration were performed at laboratory condition. The suitability of Freundlich, Langmuir, and Scatchard isotherm models was investigated for Cr(VI)-resin equilibrium. According to the results, calculated maximum ion-exchange capacities were 280.25 mg/g, 147.67 mg/g, and 163.67 mg/g of Cr(VI)/g, for Eichrom 1-X4, Lewatit M+ M800, and Lewatit A8071, respectively. The sorption kinetics and thermodynamic parameters for the equilibrium were studied for all three resins. | URI: | https://doi.org/10.1007/s12517-019-4677-5 https://hdl.handle.net/20.500.13091/757 |
