Abstract
A method for the determination of phenolic pollutants in water using an automated permeation sampler is described. Phenols permeating through a membrane are purged into a sampling tube containing Tenax‐TA adsorbent. Samples collected are thermally desorbed onto a capillary column gas chro‐matograph. Phenolic concentrations as low as 10 ppb for several phenols can be achieved by this method. The automated permeation sampler provides an alternative way to monitor concentration of phenolic pollutants. This method has several advantages over the conventional method, such as eliminating time‐consuming preconcentration steps, avoiding use of solvents and providing a high degree of automation.
