METHOD OF RECOVERING HEAVY METAL IONS FROM DILUTE SOLUTION AND APPRATUS THEREFOR |
摘要 |
<p>Heavy metal ions are recovered from a dilute aqueous solution by flowing the solution through either a single bed of ion-absorbing material in successive forward and reverse directions, or through a first bed of ion-absorbing material and thereafter through a second bed of ion-absorbing material in the reverse direction of flow. The reversal of flow is to periodically mechanically agitate a bed of ion-absorbing material to dislodge contaminants, such as gelatin.</p> |
