Abstract
Telah dilakukan penelitian tentang penentuan laju korosi ( CPR ) pelat besi dalam media pengkorosi asam klorida. Proses korosi dilakukan dengan dan tanpa arus listrik, dengan menempatkan pelat besi sebagai anoda dan batang karbon sebagai katoda. Jumlah besi terkorosi ditentukan pada variasi waktu kontak 0,5; 1,0; 1,5; 2,0; dan 2,5 jam dan variasi p H 2,0; 2,5; 3,0; 3,5; 4,0. Secara keseluruhan hasil penelitian menunjukkan bahwa dengan bertambah lamanya waktu kontak dan meningkatnya nilai p H, laju korosi ( CPR ) pelat besi semakin rendah dan laju korosi ( CPR ) pelat besi dengan arus listrik (5,75 mpy – 19,41 mpy) menunjukkan lebih tinggi dibandingkan dengan laju korosi tanpa arus listrik (1,44 mpy – 9,34 mpy).
English Abstract
A Research of corrosion rate, CPR, of iron plate in the hydrochloric acid solution has been done. Corrosion process was conducted using iron plate as an anode and carbon as a cathode either with electrical current or without an electrical current. The amount of corroded iron was determined at corrosion time of 0.5; 1.0; 1.5; 2.0; and 2.5 hours and p H variation of 2.0; 2.5; 3.0; 3.5; 4.0. The result of this research showed that increasing the duration time contact and p H values were lowering the corrosion rate, and the CPR by an electrical current (5.75 mpy – 19.41 mpy) was higher compared to CPR without an electrical current (1.44 mpy – 9.34 mpy).
