Analytical Procedures for Aniline and Selected Derivatives in Wastewater and Sludge

摘要

This study involved the development and validation of analytical methods for determining aniline and 18 halogen and nitro-substituted derivatives in industrial wastewater and municipal sludge. Gas chromatography (GC) with a nitrogen-phosphorus detector (NPD) was found to be well suited as a determinative technique for anilines in wastewater. Detection limits of 1-5 micrograms/L were achieved using both packed and capillary columns. A GC-MS approach which was essentially the same as U.S. EPA Method 625 was found to be useful for identifying and determining anilines in industrial wastewater at the low micrograms/L level. A U.S. EPA Interim Method developed by EMSL-Cincinnati for the determination of priority pollutants in municipal sludge was evaluated and optimized for the determination of anilines. Detection limits of 50-300 micrograms/kg were achieved.
