Measurement and Control of Mercury Species in Flue Gases from Liquid Waste Incineration

摘要

New measurement methods have been developed for speciation of mercury and its compounds under flue gas conditions. Total mercury can be collected by a silver denuder or by a gold-coated diffusion screen. Mercury halides can be selectively preconcentrated by a potasium chloride denuder. The use of a microwave-induced plasma source combined with optical emission spectrometry for continuous monitoring of total mercury is investigated.
