摘要:A research on the activated carbon that prepared with the candlenut shell by using H3 PO4 2,5% as the activating agent has been done. All samples were heated at the temperatures of (400, 500, and 600) o C. The activated carbon have specific surface area (6.582; 95.623; and 391.567) m2 /g respectively. Capacitor electrode for capacitive deionization (CDI) was fabricated by using activated carbon that was heated at activation temperature of 600 o C with polyvinyl alcohol (PVA) as the binder. Based on cyclicvoltammogram of electrode, specific capacitance of CDI electrode is 50.21 mF/g. To observe desalination process of electrode, CDI was made by monopolar system and immersed in NaCl 0.24 M as brackish water sample. Direct current voltage 1.2 V was applied to CDI cell. The decrease of NaCl conductivity with CDI system respectively is 61.58%. Sodium concentration in NaCl decreases from 138.000 mg/L to 80.667 mg/L about 40 minutes of desalination process.The activated carbon that prepared from candlenut shell is potential to be developed as CDI system for desalination of brakish water.
