  1. 1. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Stéphanie Nyström; [2022]
    Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).
