Adsorption and Dissolution of Carbonate Minerals

本项目将研究物种在方解石及其相关矿物表面的吸附。吸附将来自水和非水体系，并涵盖一系列极性添加剂。将使用粉状和单晶物种，并讨论被吸附物种的位置。我们还打算考虑吸附/解吸的温度依赖性，以及任何被吸附的层如何改变/减少碳酸盐固体的溶解。这项工作将在国际设施中使用基于实验室的耗尽等温线和中子反射进行实验。

This project will study the adsorption of species to the surface of calcite and related minerals. The adsorption will be from water and non-aqueous systems and cover a range of polar additives. The use of powdered and single crystal species will be used and the location of the adsorbed species will be addressed. We also aim to consider the temperature dependence of the adsorption/desorption and how any adsorbed layer might change/reduce the dissolution of the carbonate solids. The work will be experimental using lab-based depletion isotherms and neutron reflection at international facilities.
