Aqueous diffusivities and solubilities of NO were determined by using a chemiluminescence detector to measure time-dependent fluxes across stagnant liquid films confined between polydimethylsiloxane membranes. The NO diffusivities in pure water and PBS at 25°C were found to be (2.21 ± 0.02) × 10 -5 cm 2 s -1 and (2.21 ± 0.04) × 10 -5 cm 2 s -1, respectively. Although lower than most previous values for NO at room temperature, these diffusivities are very similar to those for O 2, as one would expect. Extrapolation to 37°C yielded a value of 3.0 × 10 -5 cm 2 s -1. The solubility of NO in water at 25°C was (1.94 ± 0.03) × 10 -6 mol cm -3 atm -1, in agreement with the literature. This agreement, along with the excellent fits obtained to the transient flux data (<4% rms error in each experiment), supports the validity of the simultaneously measured diffusivity. The solubility of NO in PBS at 25°C was (1.75 ± 0.02) × 10 -6 mol cm -3 atm -1. The modest (10%) reduction in solubility relative to that in pure water is consistent with the usual effects of salts on gas solubilities. © 2005 Biomedical Engineering Society.

Reduced sulfur compounds are ubiquitous components of anaerobic sediments and euxinic marine environments. They are primarily produced through a complex net of both chemically and biologically mediated reactions. This results in a wide variety of dissolved and solid inorganic and organic products. Much of the recent research effort in this area has focused on biogeochemical interactions and modelling sediment diagenesis. Several excellent reviews are available on these specific topics. However, relatively little attention has been paid to more basic inorganic chemistry of this system; the topic of this review. © 1987.

Recent precise data on the solubilities of nitrogen, oxygen and argon in distilled water and seawater are fitted to thermodynamically consistent equations by the method of least squares. The temperature dependence of the Bunsen solubility coefficient is treated using the integrated van't Hoff equation. It is shown that the Setchénow relation gives an adequate representation of the salting-out effect. Equations expressing the solubilities of these gases, as a function of temperature and salinity, in units of the Bunsen coefficient, ml/l., and ml/kg are given along with solubility tables in each of these units. © 1970.

The Solubility Data Project aims to make a comprehensive search of the literature for data on the solubility of gases, liquids and solids in liquids. Data of suitable accuracy are compiled into data sheets set out in a uniform format. The data for each system are evaluated and where data of sufficient accuracy are available values recommended and in some cases a smoothing equation suggested to represent the variation of solubility with pressure and/or temperature. A text giving an evaluation and recommended values and the compiled data sheets are published on consecutive pages.
