Amino acid has advantages such as green, economic, high efficiency, and it is becoming  an important direction of corrosion inhibitor’s researchment. This paper used electrochemical method to study Alanine and Alanine compound with potassium iodide’s corrosion inhibition to carbon steel in sulfuric acid. The experiment result shows that: in the system of 10% sulfuric, Alanine’s corrosion inhibition to carbon steel is enhanced along with the increase of Alanine’s concentration, and use Alanine alone as corrosion inhibitor the corrosion inhibition effect is not evident. After compound Alanine with potassium iodide, corrosion inhibition effect is enhanced, and when Alanine’s concentration is 300mg/L, potassium iodide’s concentration is 250mg/L, the corrosion inhibition efficiency reached 92.82%, which illustrated this two have great synergistic effect. After research on corrosion inhibitor’s effect and El-Awady dynamical model, the conclusion has come out that this corrosion inhibitor is mixed corrosion inhibitor, through physical and chemical absorption, is multiple molecular layer absorption，

300PPM，的缓蚀剂加250ppm的碘化钾，这个成本真够高
