Abstract

Inhibisi dengan menggunakan larutan asam linoleat terhadap korosi baja SS 304 dalam larutan HCl 2 M telah diselidiki menggunakan metode pengukuran pengurangan berat, dan polarisasi Tafel. Hasil penelitian memperoleh bahwa asam linoleat dapat berperan sebagai penghambat korosi untuk sistem yang diuji. Efisiensi inhibisi meningkat dengan meningkatnya konsentrasi asam linoleat. Perlakuan inhibisi dengan asam linoleat, dibahas dengan melihat adsorpsi komponen pada permukaan baja, yang kemudian membentuk semacam halangan untuk transfer muatan. Adsorpsi komponen linoleat pada permukaan baja merupakan proses yang spontan dan mengikuti adsorpsi isoterm Langmuir. Adsorpsi yang seperti itu, dapat meningkatkan energi aktivasi pada proses korosi. Efisiensi inhibisi akan mencapai optimum pada saat konsentrasi asam linoleat sebesar 350 µL/L.

The inhibitive action of the aqueous linoleic acid toward the corrosion of SS 304 in 2 M HCl solution was investigated using weight loss measurements, and Tafel polarization. It was found that the linoleic acid acts as a corrosion inhibitor for the tested system. The inhibition efficiency increases with increasing linoleic acid concentration. The inhibitive action of the extract is discussed with a view to adsorption of its components onto the steel surface, making a barrier to mass and charge transfer. The adsorption of linoleic components onto the steel surface was found to be a spontaneous process and to follow the Langmuir adsorption isotherm. It was found also that such adsorption increases the activation energy of the corrosion process. The inhibition efficiency will be optimum at 350 µL/L of linoleic acid concentration.
