Abstract

Pada penelitian ini telah dipelajari variasi komposisi elektroda grafit yang dicampur dengan lem silikon dengan perbandingan 5:1 w/w, 10:1 w/w dan 15:1 w/w untuk elektrolisis larutan NaCl. Konsentrasi larutan NaCl yang digunakan adalah 1 M, 3 M dan 5 M. Pengujian elektroda meliputi pengukuran arus sebagai variasi potensial dari -1 V sampai 1 V untuk mengetahui besarnya resistansi dari masing-masing elektroda. Resistansi elektroda grafit : lem silikon = 5:1 w/w; 10:1 w/w dan 15:1 w/w sebesar 263,15 Ω; 53,47 Ω dan 19,19 Ω. Ketiga elektroda tersebut mempunyai daya tahan yang baik terhadap elektrolisis. Pengurangan kadar ion Cl⁻ pada konsentrasi NaCl 5 M selama elektrolisis dengan elektroda grafit : lem silikon = 5:1 w/w; 10:1 w/w dan 15:1 w/w sebesar 38,34 mg/L; 76,68 mg/L dan 89,46 mg/L.

The effect of graphite electrode composition on electrolysis of NaCl solutions has been investigated. Graphite powder was mixed with silicon glue in ratio 15:1, 10:1, 5:1 w/w. NaCl concentration variation that used were 1 M, 3 M, and 5 M. The electrode tested with current was measure of a function of electric voltage scanning from -1 V to 1 V to measure the resistance of each electrode. The resistance of graphite : silicon glue electrode = 5:1 w/w, 10:1 w/w, 15:1 w/w were 263,15 Ω, 53,47 Ω and 19,19 Ω, respectively. Electrodes have good durability during electrolysis process. The peak were stable without any significant difference. Chloride reduction upon electrolysis in 5 M NaCl with graphite : silicon glue = 5:1, 10:1, 15:1 w/w were 38,34 mg/L, 51,12 mg/L and 89,46 mg/L, respectively.
