Solid-phase disk extraction of resorcinol-series phenols, the main components of oil-shale-originated phenolic pollution, is described by bed depth-service volume model. The effect of concentration (C-0 = 0.025-1.5 mg dm(-3)) and flow rate (w = 3.3-97 cm(3) min(-1)) on the dynamic capacity and the extraction rate constant. gamma for disk extraction of resorcinol (R), 5-methylresorcinol (5-MR) and 2, 5-dimethylresorcinol (2, 5-DMR) on the disk BAKERBOND Speedisk(TM) SDB is studied. The linear isotherm is revealed with distribution factors far R - 55; 5-MR - 265 and 2,5-DMR -553 (mg dm(-3))s/(mg dm(-3))(L). The proportional increase of gamma with increase in w and in C-0(-1) is proved.
