Determination of Chlorinated Hydrocarbons in Industrial and Municipal Wastewaters

摘要

The objective of the report is to present the data and the research carried out to develop an analytical test procedure for the analysis of specific organic toxic substances in effluent wastewaters. The procedure is for the analysis of nine of the 114 priority or toxic pollutants identified by the EPA as Category 3 - Chlorinated Hydrocarbons. The procedure consists of several steps, including extraction, concentration, clean up, and quantification by gas chromatography with electron-capture detection and flame-ionization. The report describes the work done leading to selection of the procedures and includes data and information on a literature search, sample preservation procedures, elution of the compounds on various gas chromatographic columns, several solvent extraction efficiencies versus pH, stability of compounds in water-soluble solvents, sample extract clean up procedures, and application of the procedures on effluent wastewaters.
