Beschreibung
Zusammenfassung:Disclosed is an electrode an electrode for capacitive deionization comprising - (i) an adsorbent having specific surface area of 100 m 2/g to 1300 m 2/g; - (ii) conductive carbon black; and - (iii) a binder; wherein said adsorbent is impregnated with a substance having conductivity in the range of 105 S/m to 107 S/m and standard hydrogen potential in the range of -0.3 V to +1.3 V. The electrode provides enhanced recovery and greater reduction in total solids and is more energy efficient. The process or preparing the electrode and a gravity fed water purification apparatus incorporating said electrode re also disclosed.
