PEMBUATAN KOMPOSIT CARBON NANOTUBES (CNT) DIKOMBINASI DENGAN KARBON AKTIF SEBAGAI ELEKTRODA FLOW-THROUGH CAPASITOR (FTC) UNTUK APLIKASI DESALINASI AIR PAYAU

Abstract

The research about optimization of composite manufacture activated carbon electrodes combined with carbon nanotubes (CNT) has been done with application in desalination for brackish water by flow-through capasitor (FTC) method. FTC is one of desalination method which performed by flowing saline solution through the gap between the electrodes based on the principle of chip (flat) parallel capacitor. Electrodes made with at least 20% binder addition and obtained by hot-pressing under pressure 20 Mpa, temperature 180 0C for 30 minutes. The results showed that the most effective combination of electrodes in separate salt is electroda with 10% CNT addition. The test of desalination prototype with 7 pairs of activated carbon electrodes with 10% CNT addition for 60 minutes can separate salt compound from salt solution 0.03 M (1785 mg /L) for 52%.
