[NMR studies of water-gas interactions].
The analysis of reported data concerning the solubility of different gases in water depending on a temperature was carried out. These dependences could be described by mono- or biexponential function. Solubilities of nitrogen and oxygen are additive and depend on their percentage in the atmosphere above the fluid. The temperature dependence of oxygen and nitrogen dissolved in water corresponds to that in the atmospheric air. The measurements of water spin-lattice relaxation times changing upon the concentration of dissolved paramagnetic oxygen showed that the oxygen could be significantly but not completely eliminated by saturation with any gases. The best method is the contact with a water immiscible liquid with higher gas capacity than water. However, it results in unstable state of a gas-water system converging to equilibrium.
