Experimental Aqueous Geochemistry

The experimental aqueous geochemistry laboratory is equipped for investigations of chemical processes at ambient pressure and temperature, and in particular experiments that require the absence of oxygen and the presence of hydrogen sulphide. Applications that have used the laboratory have included investigations of Fe and Cu isotope fractionation during sulphide mineral reactions, microbial processes in subsurface environments and reactions of magnetic minerals in bentonite matrices in order to develop monitoring technologies for geological radwaste disposal.

Laboratory equipment includes: Saffron Alpha anoxic chamber (N2 atmopshere), Anaerobic manifolds, Analytical Instrument Systems DLK60 electrochemical analyser, potentiometric analysers and sensors, LTE Mini-Lyotrap freeze drier, Camspec UV-vis spectrophotometer and Kern analytical balance.

Access to the laboratory is offered on a collaborative research basis via discussion with Dr Ian Butler
