Abstract: In this paper Xanthan gum（XG）is employed to coat microscale zero-valent iron（mZVI）for surface modification for overcoming the gravity sedimentation of mZVI and improving its remediation efficiency in chlorinated hydrocarbon polluted groundwater.The suspension stability of modified mZVI and its trichloroethylene（TCE）removal efficiency are systematically investigated by adopting different XG/mZVI ratios（0-6g/L XG:10g/L Fe）.Corresponding to XG concentration of 0,1.5,3.0and 6.0g/L,the suspension sta... More
