산 완충능력과 토양 성분이 동전기-펜톤 공정에 의한 phenanthrene 오염토양 정화에 미치는 영향 = Effect of Acid Buffering Capacity and Soil Component Remediation of Soil Contaminated with Phenanthrene using Electrokinetic-Fenton Process

다국어 초록 (Multilingual Abstract)

This research was conducted to investigate effects of acid buffering capacity and soil component in treatment of phenanthrene using electrokinetic-Fenton process. In Hadong clay of high acid buffering and low iron oxide content, it was difficult to oxidize phenanthrene due to shortage of iron catalyst and scavenger effect of carbonate minerals. The desorbed phenanthrene conductive to Fenton oxidation was transported toward cathode by electroosmotic flow. However, in Youngdong illitic clay, oxidation of phenanthrene near anode readily occurred compared to Hadong clay due to high iron content and low acid buffering capacity.
