IMPROVEMENT OF POTENTIAL STABILITY BY ANODIZING TREATMENT OF ZINC REFERENCE ELECTRODE BURIED IN SOIL
阳极氧化法提高土壤中锌参比电极电位稳定性

The industrial pure zinc buried in soil is anodized by galvanostatie polarization. The EIS and potential of electrode buried in soil for deferent time are measured and analyzed. The results are compared with those obtained on traditional zinc electrode. It is shown that changes of their characteristie with time are not remarkable, The formation process of anodic film is discussed. The potential of the polarized zinc electrode is quite stable for a long time.
