The XAD resins were found to exhibit higher specific retention volumes (Vg, net gas-phase retention volume per unit weight (gram) of sorbent) than PUF for some 3-ring PAHs at 20°C. The 3-ring compounds broke through the XAD adsorbents more easily than the 4-ring compounds at constant temperature. For the equation, Log Vg=m log PL+b (PL: subcooled liquid vapor pressure) the average m values were approximately –0.2 and –0.3 at 20 and 40°C, respectively. Moreover, the Vg values were lower at 40 oC than at 20°C for each PAH compound. The XAD-4 appeared to have a greater Vg value (adsorbent weight based) for each compound among the adsorbents at 40°C. It was possible that PAH micropore adsorption dominated on XAD-4, different from the predominance of the PAH surface adsorption on the other two adsorbents.
