VAPOR ADSORPTION OF TRICHLOROETHYLENE ON QUARTZ SANDS OF VARYING GRAIN-SIZE

Laboratory Measurements were carried out to determine the vapor adsorp tion of the solvent trichloroethylene (TCE) on a dry quartz sand of tw o different mesh sizes. Using a static adsorption laboratory procedure and inverse gas chromatography (IGC), the sorption of TCE vapor in ni trogen was measured at concentration ranges of approximately 0.1 to 44 0,000 ppm by volume. Adsorption was measured on 30/40 and 100/200 mesh dry quartz sand, with the finer material created by mechanically crus hing and sieving coarser material. The observed sorption isotherms fit a Freundlich isotherm and arc also well represented by a simple linea r sorption isotherm.
