A passive sampling technique for the determination of time-weighted-average concentrations of phenolic priority pollutants in water is described. Phenols permeate a silicone polycarbonate membrane and are collected on a polymeric adsorbent. For high concentration ranges, phenols are adsorbed on the XAD-7 resin and then desorbed with acetonitrile. Low ppb concentrations of phenols are analyzed by collection on Tenax-TA followed by thermal desorption. Separation and quantification is achieved by capillary column gas chromatography using a flame ionization detector. A linear relationship between the amount of phenols collected and the products of the exposure time and phenolic concentrations over the range of 5 ppb - 20 ppm have been determined. Temperature and solution pH affect permeation rates of the phenols. The sampling method is simple, inexpensive and suitable for multilocation monitoring. |
