영가철에 의한 과황산의 활성화 및 유기물질의 산화분해 = Oxidation of Nitrobenzen by Persulfate Activated by Zero-Valent Iron

다국어 초록 (Multilingual Abstract)

Persulfate is one of the popular oxidants which can be used for in-situ chemical oxidation (ISCO) since it has moderate stability in soil and groundwater environment and relatively strong oxidation power through activation. The common activation methods such as UV, heat, and base cannot be applied or have limitations in soil environment. Current study tested a reductive activation of persulfate using zero-valent iron (ZVI) which has been used for permeable reactive barrier. ZVI successfully activated persulfate and oxidized a model target organic contaminant, nitrobenzene. Increased persulfate concentration led to an increased reaction rate up to a point and the degradation rate was not increased from the point. The increased dose of ZVI also increased the reaction rate at a fixed dose of persulfate indicating the dose of activator is one of the factor controling the reaction rate.
