    Author : Kajsa Engström; [2021]
    Keywords : Chemical stabilisation; soil remediation; contaminated soil; in situ pilot scale; sacrificial iron;

    Abstract : In Boden, northern part of Sweden, there is a site called Solgårdarna which has been used for wood impregnation. The activities on the site have led to soil contamination with chrome (Cr), copper (Cu) and arsenic (As), where the arsenic contamination is the most problematic. READ MORE

  3. 17. Remediation of an arsenic-contaminated anoxic aquifer in hjältevad with zerovalent iron : assessment and modelling of sorption strength and solubility of arsenic

    University essay from SLU/Dept. of Soil and Environment

    Author : Kathrin Leicht; [2021]
    Keywords : arsenic remediation; zerovalent iron; anoxic aquifer;

    Abstract : In-situ injection of zerovalent Iron (ZVI) particles to remediate contaminated groundwater is a widely applied approach. However, studies assessing the remediation and immobilisation mechanisms of Arsenic (As) under anoxic field conditions with zerovalent iron particles are lacking, especially for nanosized sulphidated ZVI (S-nZVI) and oxidic shell free ZVI (OSF-nZVI).
