제목 Electrostatic field assisted lithium recovery process from aqueous solution using lithium selective adsorbent
초록 In this study, the effect of ectrostatic field assistance (EFA) was investigated to improve the conventional lihtium recovery method which requires long adsorption/desorption time. The operation of the experiments was conducted on the continuous flow through system equipped test set by modifying the conventional membrane capacitive deionization (MCDI) system. The adsorption/desorption performance by EFA range from 0 to 2.0 V was compared to that of the conventional process. The results showed that the adsorption performance by EFA enhanced with increasing cell potential up to 1.0 V and initial lithium concentrations, also the adsorption rate reach at equilibrium state was significantly enhanced under EFA compared with physisorption condition. The system showed good durability during the repeated adsorption/desorption cycle tests.
