Carbon Material-Based Flow-Electrode Capacitive Deionization for Continuous Water Desalination

Flow-electrode capacitive deionization (FCDI) offers an electrochemical, energy-efficient technique for water desalination. In this work, we report the study of carbon-based FCDI, which consists one desalination chamber and salination applies a carbon nanomaterials-based flow electrode that circulates between cell anode cathode, to achieve fast, continuous process. Five different nanomaterials were used preparing studied performance, with properties including average salt removal rate (ASRR), efficiency (SRE), energy consumption (EC) charge (CE) being quantitatively determined comparation. Different FCDI parameters, concentration voltage, investigated examine influences on Long-term operation was evaluated using optimal results found in conditions 1.5 M concentration, V 20 mL min−1 streams. The showed ASRR 63.7 µg cm−2 min−1, EC 162 kJ mol−1, CE 89.3%. research findings validate good new technology suggest its potential real, long-term application.
