Partitioning of volatile halocarbons between surrogates for atmospheric solid aerosols and gas phase as examined by tpd ms and inverse gas chromatography
The desorption non-isothermal kinetics of preliminary adsorbed Cl, Br, and I-containing volatile halocarbons from the surface of surrogates for atmospheric solid aerosols (fumed silica and alumina, silica gel and H-mordenite) was studied by TPD MS.
