Abstract
This study deals with the so-called isotope salt effect associated with the presence of salts in oceanic and other natural waters. We have estimated this effect both for deuterium and oxygen-18, taking advantage of accurate gas–water equilibration methods. Solutions composed of either monovalent or divalent salts and of a mixture of these different salts with a composition similar to seawater have been studied for concentrations of 0.5, 1 and 2 times that of seawater. We confirm that the deuterium salt-effect varies linearly with the molality of the solution and we have checked that this relation applies to low molalities. This result is of direct use for the measurement of δ D in saline waters by the H 2–H 2O equilibration method. There is no significant oxygen-18 salt effect for this range of concentrations.
