Trichloroethylene (TCE) is a representative dense nonaqueous phase liquid (DNAPL) in groundwater. TCE as a form of free fluid has been treated by surfactant-enhanced aquifer remediation (SEAR). After application of SEAR, groundwater contains little amount of residual TCE and surfactant. Residual TCE

Slag, which consists of calcium oxide, aluminium oxide, and other metal oxides, is an abundant by-product in steel-making process. It has been used as adsorbents to remove various heavy metals and the major removal mechanisms are precipitation and adsorption on the surface of metal oxide. However, t
