Results showed that aqueous U concentration increased continuously with a solubilization rate of 0.16 mgm-2h-1 for the first 564 d (1.5 y). After 1.5 y, U concentration reached a maximum value (saturation) and decreased afterwards. The saturation concentration of 54 mgL-1 (mean value) was influenced to various extent by the presence of carbonate minerals. Dissolution/precipitation, adsorption or ion exchange processes appear to control U solubilization."],["dc.format.extent","425-435"],["dc.format.mimetype","application/pdf"],["dc.identifier.doi","10.1007/3-540-28367-6_42"],["dc.identifier.fs","48807"],["dc.identifier.ppn","587490810"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/5057"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/91825"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.publisher","Springer"],["dc.publisher.place","Berlin/Heidelberg"],["dc.relation.ispartof","Uranium in the Environment"],["dc.relation.orgunit","Fakultät für Geowissenschaften und Geographie"],["dc.rights","Goescholar"],["dc.rights.access","openAccess"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","550"],["dc.title","Characterizing uranium solubilization under natural near oxic conditions"],["dc.type","book_chapter"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","submitted_version"],["dspace.entity.type","Publication"]]

The concept of “features, events and processes” (FEP) refers to identifying and selecting the most relevant factors for safety assessment studies. In the context of hydraulic fracturing we constructed a comprehensive FEP database and applied it to six key focused scenarios defined under the scope of FracRisk project (http://www.fracrisk.eu, last access: 17 August 2018). The FEP database is ranked to show the relevance of each item in the FEP list per scenario. The main goal of the work is to illustrate the FEP database applicability to develop a conceptual model for regional-scale stray gas migration."],["dc.identifier.doi","10.5194/adgeo-45-185-2018"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15379"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59364"],["dc.relation","info:eu-repo/grantAgreement/EC/H2020/636811/EU//FracRisk"],["dc.relation.issn","1680-7359"],["dc.subject.ddc","550"],["dc.title","Conceptual model development using a generic Features, Events, and Processes (FEP) database for assessing the potential impact of hydraulic fracturing on groundwater aquifers"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

The long term stability of this immobilized U is yet to be addressed. The presented study investigates the remobilization of U(VI) from iron oxides via diverse reaction pathways (acidification, reduction, complex formation) in the laboratory. Prior uranium co-precipitation experiments were conducted under various conditions. The addition of various amounts of a pH-shifting agent (pyrite), an iron complexing agent (EDTA) or an iron (III) reduction agent (TiCl3) yielded in uranium remobilisation to concentrations above the US EPA maximum allowed contaminant level (MCL = 30 mg/L).
