Abstract

Intisari Salah satu sumber daya air yang belum dimanfaatkan sebagai sumber air minum secara maksimal adalah air laut. Pada artikel ini, dilaporkan hasil penelitian tentang pembuatan sistem elektroda Capacitive Deionization (CDI) dengan metode crosslinking dari perpaduan bahan karbon aktif tempurung kelapa, crosslinker glutaric acid dan polimer polyvinyl alcohol. Optimasi sistem desalinasi dilakukan dengan memvariasi potensial sumber listrik, dan penambahan membran untuk pertukaran ion. Pengujian sistem dilakukan dengan uji konduktivitas pada air yang dihasilkan pada proses desalinasi. Perubahan konduktifitas larutan ini menunjukkan perubahan adsorpsi ion-ion NaCl pada elektroda sistem CDI. ABSTRACT Sea water is one of the water resources that has not fully utilized for drinking water. In this paper, the electrodes of Capacitive Deionization (CDI) were synthesized by crosslinking method. The electrodes were synthesized with an activated carbon from coconut shell, glutaric acid and polyvinyl alcohol as a binder. Furthermore, optimization of desalination system is done by variation of voltage source (V) and the addition of ion exchange membrane. The system was tested by conductivity measurement of water before and after desalination process. Resulted conductivity level from measurement showed that the process of NaCl adsorption is occurred on the electrodes.
