Abstract

Pendeposisian nikel dari larutan garam nikel sulfat dengan metode elektrolisis telah dilakukan. Kondisi proses dibuat pada variasi konsentrasi nikel sulfat: 0,258 M, 0,323 M dan 0,388 M, dengan variasi luas anoda 0,1099 dm2, 0,1413 dm2 dan 0,1727 dm2. Hasil pendeposisian adalah massa elektrodeposit. Dari percobaan yang telah dilakukan, diperoleh massa elektrodeposit terbesar pada konsentrasi nikel sufat 0,388 M, luas anoda 0,1727 dm2 dan rapat arus 0,454 AJdm2 dengan massa elektrodeposit nikel 23,4 mg, sedang massa elektrodeposit terkecil pada konsentrasi nikel sulfat 0,258 M, luas anoda 0,1099 dm2 dan. 'rapat arus 0,495 A/dm2 dengan massa elektrodeposit 12,1 mg. Konsentrasi nikel sulfat dan luas anoda berpengaruh terhadap massa elektrodeposit. Peningkatan konsentrasi nikel sulfat dan luas anoda menyebabkan peningkatan massa elektrodeposit. Electrodeposition of nickel sulphate salt by electrolisis method has been done. Condition of processes was made as follow nickel sulphate consentration variation 0.258 1V1, 0.323 M and 0.388 M anoda s follow area of anoda variation 0.1099 dm2, 0.1413 dm2 and 0.1727 dm2 , Electrodeposition product is electrodeposition mass. From this research, maximum deposit was obtained at nickel sulphate consentration 0.388 M, area of anoda 0.1727 dm2 and current density 0.454 AJdm2, with electrodeposit mass 23.4 mg, and minimum deposit was obtained at nickel sulphate consentration 0.258 M, area of anoda 0,1099 dm2 and current density 0.495 A/dm2 , with electrodeposit mass 12.1 mg. Nikel sulphate consentration and area of anoda influence to electrodeposit mass. Increase of nickel sulphate consentration and area of anoda to cause increase of electrodeposit mass. xiv
