Abstract
In
this paper, Reversed-Flow Gas Chromatography (RF-GC) is utilized to
investigate the evaporation of low molecular weight alcohol. Evaporation
rates as well as the diffusion rates of methanol are determined with a
surfactant monolayer on the surface of the liquid; while nitrogen acts
as carrier gas, at 313 K. The precision (>99.9) and accuracy of this
investigation demonstrates the potential of current methodologies for
environmental impact studies; this is further verified when the results
are compared with the available literature. The varying evaporation
rates of methanol in the presence of varying amounts of Triton X-100
reflects that application of surfactants do damper the evaporation rates
of liquid pollutants; without interference with the formers diffusion
coefficients. High amounts of Triton X-100 are required for retardation
of evaporation rates, suggesting the formation of a densely packed
surface monolayer or the formation of an insoluble monolayer.
