悬浮电解去污配方的去污能力及电化学性能测试

利用自制的悬浮电解去污装置对碳钢/不锈钢模拟污染样片进行电解去污。去污结果表明：H₂SO₄-Na₂SO₄体系的悬浮电解去污配方对碳钢/不锈钢模拟污染样片能有效去污。在电解电压6V时，碳钢模拟污染样片经过2h去污，表面放射性活度可降低到本底水平；不锈钢模拟污染样片经过3h去污，去污系数可以达到180。电化学性能测试表明，该电解去污配方能有效防止阳极极化，并且在电解去污过程中具有良好的稳定性。

Decontamination Ability and Electrochemical Performance of Suspension Electrolysis Decontamination Formulations

The simulated samples of carbon & stainless steel were decontaminated by the suspension electrolysis decontamination device designed by our laboratory. The results of decontamination show that suspension electrolysis decontamination formula mainly contains sulfuric acid and sodium sulfate. When the electrolytic voltage is 6 V, for the simulated carbon steel samples, after 2 h decontamination, their surfacial radioactivity can drop to the background level; for the simulated stainless steel samples, after 3 h decontamination, their decontamination factor can reach 180. The electrochemical performance analysis show that the suspension electrolysis decontamination formula can prevent anodic polarization effectively, and have a good stability in the operation of electrolytic decontamination.
