Deuterium Isotope Effects on the Limiting Molar Conductivities of Strong Aqueous Electrolytes from 25 °C to 325 °C at 20 MPa

Plumridge, Jeffrey 02 January 2014 (has links)
State of the art conductivity equipment has been used to measure deuterium isotope effects on the molar conductivity of strong electrolytes in the temperature range of 298 K to 598 K as a means of exploring solvation effects under hydrothermal conditions. Individual ionic contributions were determined by extrapolation of published transference number data to elevated temperature. The temperature dependence of the Walden product ratio indicates that there is little difference in the transport of ions between light and heavy water . Excess conductivity observed in hydrogen and deuterium compounds arising from proton hopping in hydrogen-bonded networks has been determined in the temperature range of 318 K to 598 K for the first time
