Abstract
The present disclosure relates to a method and device for detecting mercury isotopes in crude oil. The device comprises an enrichment-absorption system and a secondary purification-enrichment system for mercury isotopes, wherein the enrichment-absorption system includes an air-background mercury absorption system, a pyrolysis/cracking system, a mercury-sample absorption system connected in series with pipe lines, and a vacuum pump, and the vacuum pump is connected to the mercury-sample absorption system through a pipe line; the secondary purification-enrichment system includes a nitrogen-gas cylinder, a collection bottle with potassium permanganate absorption liquid, and a secondary enrichment-absorption bottle connected in series with pipe lines, wherein the secondary purification-enrichment system further includes a stannous-chloride storage bottle, which is connected to a pipe line between the nitrogen-gas cylinder and the collection bottle with potassium-permanganate absorption liquid via a peristaltic pump and through a pipe line.
