The inhibiting effect of sodium molybdate on mild steel corrosion in deaerated and low-oxygen concentration waters at pH 9.0 and 60 C was investigated using weight loss and electrochemical test methods. Molybdate was inhibitive at a water oxygen concentration between 1 and 2.5 mg/L. In combinations with sodium nitrite, molybdate exhibited synergistic inhibition at 1 mg/L oxygen. An explanation of the observed synergism is discussed based on the electrochemical study.
