Rapid biologically mediated oxygen isotope exchange between water and phosphate
[1] In order to better constrain the rate of oxygen isotope exchange between water and phosphate via biochemical reactions a set of controlled experiments were conducted in 1988 at the Aquaculture Plant in Elat, Israel. Different species of algae and other organisms were grown in seawater tanks under controlled conditions, and the water temperature and oxygen isotopic composition (dOw) were mon...

متن کاملCalculations of the Oxygen Isotope Fractionation between Hydration Water of Cations and Free Water
The oxygen isotope fractionation factors between the hydration complex of the alkali ions in the gas phase and a free water molecule have been computed on the basis of the energy surfaces calculated by Kistenmacher, Popkie and Clementi for a water molecule in the field of an alkali ion. For comparison with recently measured oxygen isotope fractionation factors in aqueous alkali halide solutions...
متن کاملClumped Isotopic Equilibrium and the Rate of Isotope Exchange between Co2 and Water
The reaction of CO2 hydration/dehydration controls the oxygen isotopic composition in both carbonate minerals and atmospheric CO2 through the exchange of oxygen isotopes with water. The use of O as an environmental indicator typically assumes isotopic equilibrium, namely full oxygen isotope exchange between CO2 and water. Clumped isotopes is a new isotopic tracer that is used in both CaCO3 and ...
متن کاملA new value for the stable oxygen isotope fractionation between dissolved sulfate ion and water
Although the stable oxygen isotope fractionation between dissolved sulfate ion ðSO 4 Þ and H2O (hereafter aðSO2 4 –H2OÞ) is of physico-chemical and biogeochemical significance, no experimental value has been established until present. The primary reason being that uncatalyzed oxygen exchange between SO 4 and H2O is extremely slow, taking 10 5 years at room temperature. For lack of a better appr...
