Investigating the Environmental Stability of Potential Materials for Remediation

Dr Caroline Kirk School of Chemistry, University of Edinburgh This presentation will explore three different systems, focussing on the use of advanced synchrotron studies to investigate structures and stabilities of materials under different environmental conditions: 1. Investigating the environmental stability of synthetic analogues of metatorbernite-type (Cu(UO2)2(PO4)2.8H2O) minerals; these mineral phases are being explored for use in a remediation of U(VI)-containing waste and contamination; 2. Ettringite (Ca6[Al(OH)6]2(SO4)3.26H2O): a possible remediation material? We are exploring the possible remediation of hexavalent chromium and selenium using the mineral ettringite; 3. Sustainable Cements – influence of alternative fuels on reactivity and durability of cement; this study focuses on investigations of the possible interactions between impurities coming from fuel sources during clinker production and the main clinker phase alite (C3S Ca3SiO5) and monitoring the hydration behaviour as a function of the foreign ion(s) present.
