CYSTEINE AS A GREEN CORROSION INHIBITOR FOR CARBON STEEL IN CO2 AERATED 1% NaCl SOLUTION WITH BUFFER CONTROL-pH

CYSTEINE AS A GREEN CORROSION INHIBITOR FOR CARBON STEEL IN CO2 AERATED 1% NaCl SOLUTION WITH BUFFER CONTROL-pH

<p>Corrosion on the exterior pipes can inhibited by coating or cathodic protection, but not in the interior sides. It can only be solved by the addition of corrosion inhibitor. In this research, cysteine as a green corrosion inhibitor of carbon steel in CO2 aerated 1% NaCl solution with buffer...
