3차원 토양 실험장치에서 동전기-펜턴 공정의 전기삼투흐름 모사
Abstract
Removal of phenanthrene by electrokinetic method combined with Fenton-like process was studied in a model system. The scale of reactor was 100cm in length, 100cm in width, and 70cm in height. The distance between electrodes was 70cm. Indonesia kaoline was selected as a model soil. When constant voltage of 100 V was applied to this system, current decreased from 200 mA to 100 mA for 14 days. Total accumulated EOF was about 55,000 mL. The concentration of phenanthrene near anode was very low because direction of electroosmosis was from anode to cathode and hydrogen peroxide was supplied to anode reservoir. Phenanthrene concentration was increased as the location was far from anode because hydrogen peroxide was gradually decomposed and then the rate of hydroxyl radical production was decreased.
