Parametric studies on the performance of mixed-bed ion exchange for silica removal at ultralow concentrations |
| 초록 |
We experimentally evaluated the performance of mixed-bed ion exchange for silica removal under the various conditions in the concentration range used for ultrapure water processing. Data were collected in the batch and the continuous column systems with Dowex Monosphere resins used commercially for ultrapure water applications. The equilibrium and the breakthrough curves of silica, plotted as the concentration ratio versus run time, give detailed results about the effects of temperature, cation resin ratio, initial concentration, and volumetric flow rate on the performance of mixed-bed ion exchange unit for silica removal. The selectivity coefficients of the anion resin for silica over hydroxide ion were obtained as a function of temperature. The results of the present study will be used to develop and simulate mathematical models and to understand the performance of mixed-bed ion exchange unit for silica removal at ultralow concentrations. |
