Estimation of the Enhancement Factor for Mercury in Air
نویسنده
چکیده
A combination of classical thermodynamics and molecular theory was used to calculate the enhancement factor (ratio of vapor-phase partial pressure to saturated vapor pressure) for liquid mercury in equilibrium with air at standard atmospheric pressure at temperatures from 0 ◦C to 40 ◦C. The enhancement factors range from 1.0025 at 0 ◦C to 1.0016 at 40 ◦C. This enhancement is too small in magnitude, and in the wrong direction, to explain a difference that has been noted between equilibrium vapor concentrations implied by the vapor pressure of pure mercury and those assumed in some calibration procedures.
