Inhibition Effect of Sodium Nitrite and Triethanolamine for Uranium by Electrochemical Methods

摘要：

　　The corrosion inhibition effect of sodium nitrite (NaNO2) and triethanolamine (N(C2H4OH)3) for uranium was evaluated in 200 mg/L sodium chloride (NaCl) solution by linear polarization and potentiodynamic polarization.The results showed that NaNO2 predominatly acted to inhibit the anodic reaction for the electrochemical behavior of uranium.NaNO2 combined with N(C2H4OH)3 could reinforce corrosion resistance of uranium.Multi-function could be found from 20 g/L NaNO2 combined with 10 ml/L N(C2H4OH)3.Pitting corrosion on uranium surface could be effectively prevented by 1 g/L NaNO2 combined with 10 ml/L N(C2H4OH)3.Auger electron spectroscopy (AES) and Raman spectrum analyses indicated that uranium oxide layer mainly contained uranium dioxide (UO2).
