  • Measurement of the diffusion coefficient of sulfur

    Abstract. Sulfur hexafluoride has been widely used in field studies and laboratory experiments to develop a relationship between gas transfer and wind speed. The interpretation of the data from such studies requires the diffusion coefficient of SF 6 ( Dgaz sf6 ), which has not previously been measured. In this study, Dsf6 gas has been determined in pure water and in 35‰ NaCl over a temperature range of 5–25°C.
