On-Line Zeeman Atomic Absorption Spectroscopy for Mercury Analysis in Oil Shale Gases

摘要

This publication describes the development and initial testing of instrumentation for continuous on-line analytical measurement of mercury concentrations in complex gas streams or in ambient air, in the presence of smoke, organic vapors, and oil mist from oil shale processing plants. The technique was Zeeman atomic absorption spectroscopy. The mercury monitor described is not susceptible to interferences which plague other methods and thus may be used to characterize mercury emissions on a realtime basis. This mercury monitor will find immediate application for the characterization of synfuel and other industrial emissions, mobile source identification, and environmental health monitoring.
