| 英文摘要 | Vanadium is recognized as a potentially dangerous pollutant following closely behind lead, mercury and arsenic. Vanadium removal from wastewater prior to discharge is essential. In this work, an amorphous hydrated chromium oxide was prepared and its vanadium adsorption ability studied. As prepared, the hydrated oxide showed high efficiency in vanadium adsorption 鈥?e.g., from 300 to 0.75 mg-V路L1. The effects of pH, adsorbent dosage, temperature, adsorption time and the presence of other ions on the vanadium removal rate were investigated, and optimal parameters determined. Dynamic adsorption results showed that pseudo-second-order kinetics could be used to interpret the kinetic curve and that the process was that of chemisorption. The Langmuir isotherm was found to fit the adsorption behavior well. 漏 2021 The Authors. |
