Comparison of carbon materials for capacitive deionisation

Popis výsledku v původním jazyce

Water treatment is a very important process. The large amount of water has to be treated worldwide. The most ordinary methods are distillation, reverse osmosis and electrodialysis at present time. Another promising process is capacitive deionisation (CDI) intensively studied in recent years. CDI is a very simple process for salinity reduction of treated water. The key components of CDI are high surface electrodes. Electrodes are usually from carbon material. Electrodes have to exhibit high specific surface area and pore structure suitable for ions capturing. The present work is focused to the comparison of different carbon electrodes. Selected commercial and in house made electrodes were examined in the simple bath cell by cyclic voltammetry and potential pulse chronoamperometry. Potential range ±1.2 V was used for maximum ions captured on surface of electrode and to avoid undesired Faradaic reactions. Two selected electrodes were measured in the plug flow cell by potential pulse chronoamperometry. The solution conductivity at the cell output was measured in time. The conductivity was recalculated to the concentration.
