Layer-structure materials have attracted considerable interest for the removal, separation, and preconcentration of trace metals in analytical and environmental chemistry. In the present work, we developed a separation and preconcentration method for lithium ions from water samples using K-birnessite with ...
The full-time cycle at 0.25 Ag−1 for LIG@0.2M was 290 s, as shown in Figure 5a. With increasing the current density, the full-time decreased to a lower value. The discharge time of LIG@0.2M was observed between 128 to 6 s when the current density increased from 0.25 to 3.0 Ag...
