1. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. READ MORE

2. 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 EnvironmentAbstract : 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).

3. 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 EnvironmentAbstract : 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).
