New procedure for the examination of the degradation of volatile organonitrogen compounds during the treatment of industrial effluents
Abstract
We present a new procedure for the determination of 32 volatile organonitrogen compounds in samples of industrial effluents with a complex matrix. The procedure, based on dispersive liquid–liquid microex-traction followed by gas chromatography with nitrogen-phosphorus and mass spectrometric detection, wasoptimized and validated. Optimization of the extraction included the type of extraction and disperser sol-vent, disperser solvent volume, pH, salting out effect, extraction, and centrifugation time. The procedurebased on nitrogen-phosphorus detection was found to be superior, having lower limits of detection (0.0067–2.29 μg/mL) and quantitation as well as a wider linear range. The developed procedure was applied tothe determination of content of volatile organonitrogen compounds in samples of raw effluents from theproduction of bitumens in which 13 compounds were identified at concentrations ranging from 0.15 to10.86 μ g/mL and in samples of effluents treated by various chemical methods.
