Cartridges containing solid adsorbents between layers of polyurethane foam (PUF) were evaluated for collecting chlorobenzenes, chlorophenols, hexachlorocyclohexanes (HCHs), and two-ring aromatic hydrocarbons. The cross-section glass cartridges, packed with Tenax (5-10 g), XAD-2 (14-16 g), or Florisil (30 g) between two 2.5-cm thick PUF slices, were designed to fit into the head of a General Metal Works PS-1 sampler. An inlet was built to vaporize test compounds into a clean airstream and sweep them into the adsorbent traps. Collection efficiency experiments at 20 deg C were conducted by injecting test compounds into the sampling train and determining by mass balance the percentages recovered from the traps. Retention volumes and theoretical plate numbers were determined for dichlorobenzene elution bands on PUF-Tenax cartridges. Dichlorobenzenes and two-ring aromatic hydrocarbons were collected from up to 165 cu. m air on PUF-Tenax (10 g Tenax), with mass balances averaging 88%. At 285-372 cu. m air, mass balances for tetra- through hexachlorobenzenes and HCHs averaged 89% on PUF-Tenax (5 g Tenax), 80% on PUF-XAD-2, and 78% on PUF-Florisil. Di- and trichlorophenols were collected without breakthrough by PUF-Tenax, but low recoveries were observed for pentachlorophenol and 2,3,4,5-tetrachlorophenol. Recoveries of chlorophenols were poorer from PUF-Florisil than from PUF-Tenax or PUF-XAD-2.
