Abstract

Effective diffusion coefficient and partition coefficient are essential parameters to quantitatively assess the adverse impact of contaminated or stabilized soil on surrounding environment. In this study, a new method is developed to back-calculate the effective diffusion coefficient and partition coefficient of contaminants in the stabilized soil. Furthermore, the migration characteristics of Pb, Zn and Cd in a novel phosphate-based binder stabilized soil are investigated. The test results show that the effective diffusion coefficients of Pb and Zn (8.5 × 10−13 m2/s and 7 × 10−13 m2/s) in the stabilized soil are significantly lower than that of Cd (1.5 × 10−12 m2/s). While the partition coefficients of Pb and Zn (8200 mg/L, 4500 mg/L) are significantly higher than that of Cd (2100 mg/L).
