This study aims to evaluate the voltage in BEDI (bipolar membrane electro-dialysis deionization) on the indium ion desorption process for the recovery of indium ions. The Voltage influence indium ion recovery are evaluated. The research findings show that in the desorption of VSB-5 indium ions, the lower the pH, the higher the desorption rates. When the voltage was 6.5 V per sheet, the desorption rates efficiency was best another condition. When the number of bipolar membrane sheets was 4, it was possible to control 4 the pH to under 4, a level at which lithium ions adsorbed onto LMO might affect the desorption phenomenon. |
