One-step sample preparation technique for broad spectrum gas chromatographic/mass spectrometric determination of organic priority pollutants in water.
A rapid and cost-effective sample preparation technique is described for the qualitative and quantitative determination of a broad spectrum of organic contaminants in water. The technique involves simultaneous-in-situ acetylation of phenols with acetic anhydride and one-step extraction of phenol acetates and basic and neutral organic compounds from water. The extract is concentrated and analyzed by gas chromatography/mass spectrometry. The recovery and precision data of selected base, neutral, and phenolic compounds are given. The advantages and disadvantages of the in-situ acetylation/extraction technique are discussed.
