Design techniques drinking water

In most laboratories today, PAHs are routinely monitored under EPA Method 8270 and comprise the majority of neutrals under the Base, Neutral, Adds (BNAs) designation of the method (2). This is a liquid-liquid extraction method with determination by gas chromatography-mass spectrometry (GC MS). Careful changes in pH of the aqueous phase enables a selective extraction of bases and neutrals from acidic compounds. Examples of priority pollutant organic bases include aniline and substituted anilines. Examples of priority pollutant organic acids include phenol and substituted phenols. The most popular method of recent years has been EPA Method 525, which incorporates SPE techniques and is applicable to PAHs in drinking water (3). [Pg.483]
