Use of macroreticular resins in the analysis of water for trace of organic contaminants
Organic impurities in water can be isolated by sorption on a small column of a macroreticular resin. The organics are readily eluted by diethyl ether; the elute is then concentrated by evaporation, and the organics are separated and determined by gas chromatography. Studies on a large number of model compounds added to water int he 10to 100-ppb range (20 parts per trillion for pesticides) demonstrated that this method is accurate and reliable. An extensive study of the procedure revealed serveral critical steps where proper technique and conditions are essential to avoid serious error. These include resin purification and handling, preparation of standard samples containing organic impurities, and the technique and apparatus used in concentrating the XAD column eluate.
