Ion Exchange Performance of Zeolite for Removal of Calcium in a CKD Leaching Solution |
| 초록 |
In the study, zeolite was used as an ion-exchange substance to remove calcium in cement kiln dust (CKD) leachate by an ion-exchange method. The CKD leachate was contained a high concentration of potassium chloride and 1,000 mg/L of calcium. Five types of zeolite were used, and 13X zeolite was observed the high calcium removal performance. We confirmed that a calcium removal amount of 13X zeolite was 13.4 mg of Ca2+/g Zeolite by ICP analysis. The high performance of 13X zeolite were attributed low Si/Al ratio and binding with sodium ion.
