Abstract

This present was carried out to evaluate the adaptability of stabilization method which was used industrial byproducts as the stabilization agency in the abandoned mine site. In order to investigate stabilization effect on As-contaminated soils treated by industrial by-products, batch tests and column tests were carried out with As-contaminated soils collected from farmland around the abandoned mine site. ZVI(zero valent iron) and SRS(steel refining slag) was shown a good treatment effect. After the column test, sequential extraction test and simple bioavailability extraction test(SBET) were carried out to analysis of the soil, and scanning electron micrograph(SEM) analysis was carried out to compare the morphology and structure of ZVI and SRS before and after reacting with arsenic in the soil. As a result, ZVI and SRS were shown 93%, 62% reduction of As concentration respectively by comparison with untreated soils. Therefore, if ZVI and SRS are used as treatment materials in As-contaminated soils, it is expected that the As leaching from soils is reduced effectively.
