Inhibisi Korosi Baja SS 304 dalam Media 1 M H2SO4 oleh Kinina dengan Penambahan 1 mM Natrium sitrat

Abstract

Kemampuan kinina sebagai inhibitor korosi baja SS 304 dengan dan tanpa penambahan 1 mM natrium sitrat dalam media 1 M H₂SO₄ telah dikaji dengan metode Electrochemical Impedance Spectroscopy (EIS). Adanya perubahan peremeter EIS (hambatan polarisasi , R_p dan Unsuf fase konstan, CPE_d) mengindikasikan adanya adsorpsi kinina pada permukaan baja membentuk lapisan film protektif. Efisiensi inhibisi yang dihasilkan meningkat seiring dengan meningkatnya konsentrasi kinina, dengan inhibisi tertinggi pada konsentrasi 500 mg/L. Penambahan 1 mM natrium sitrat ke dalam larutan uji menyebabkan efisiensi inhibisi menurun dan laju korosi baja SS 304 meningkat. Hal ini menunjukkan bahwa kinina tidak memiliki efek sinergis jika dicampurkan dengan 1 mM natrium sitrat
