Alternate Cathode Materials for Determination of Oxygen Diffusion Rate and Reduction-Oxidation Potential in a Soil Environment

使用交替电极材料的电化学研究，这种材料更完整，不受土壤化学和土壤微生物活性的综合影响。具体目标包括：研究石墨复合材料和稀土氧化物电极在溶液相中以及在有氧和厌氧土壤环境中的电化学稳定性和再现性方面的电化学行为;表征上述电极在溶液相中和土壤环境中的电化学寿命;和评估这些类型的电极的可行性作为ditu指标的生物活性负责降解土壤环境中的有机化合物。

Electrocheimical studies using alternate electrode materials which are more integral and impervious to the combined effects of the soil chemistry and soil based microbial activity. Soecific objectives include: Investigate the electrochemical behavior of graphite composite and rare-earth oxide electrodes in the solution phase as well as in both aerobic and anaerobic soil environments with regard to electro-chemical stability and reproducibility; Characterize the electrochemical lifetime of the aforementioned electrodes in both the solution phase and in soil environments; and Evaluate the viability of these types of electrodes as in ditu indicators for biological activity responsible for degrading organic compounds in soil environments.
