Study of different electrode materials for capacitive deionisation in the batch cell and the plug flow cell

Original language description

The large amount of water has to be treated worldwide. A capacitive deionisation (CDI) is promising process 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 pores suitable for ion 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 and in the plug flow 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. In the plug flow cell concentration changes were measured in the time. The commercial material Kynol(R) has shown high capacity at low potential sweep velocity. But, it was found low capacity at high potential sweep velocity. The high capacity of this electrode can be utilized if time for ion transport to the electrode will be sufficient during CDI operation regime. It was confirmed also in the plug flow cell. The higher desalination level was reached at low volumetric flow of treated solution.
