Analysis of Organic Materials in Wastewater Effluents After Chlorination

Abstract

Sewage wastewater effluent from the Denton, TX municipal treatment plant has been examined before and after laboratory chlorination. Neutral organic materials were concentrated by adsorption on Amberlite XAD-2 macroreticular resin followed by elution with diethyl ether. Gas chromatographic analysis of the extracts after concentration was carried out using flame ionization, electron capture, and Coulson electrolytic conductivity detectors. New chlorine-containing organics were observed by the Coulson detector in the chlorinated effluent using as little as 10 mg/l of total available chlorine.
