Determination of mercury in naphtha and petroleum condensate by photochemical vapor generation atomic absorption spectrometry

Determination of Total Mercury by Vapor Generation In Situ Trapping Flame Atomic Absorption Spectrometry

The analytical performance of non-chromatographic coupled hydride generation, integrated atom trap (HG–IAT) atomizer flame absorption spectrometry (FAAS) systems were evaluated for the determination of total mercury in environmental samples. Mercury, using formation of mercury vapors were atomized in air-acetylene flame-heated IAT. A new design of vapor generation integrated atom trap flame ato...

Determination of mercury(II) ion by electrochemical cold vapor generation atomic absorption spectrometry.

A technique for determination of mercury is described; it is based on electrolytic reduction of Hg(II) ion on a graphite cathode, the trapping of mercury vapor and its volatilization into a quartz tube aligned in the optical path of an atomic absorption spectrometer. The electrochemical cell consisted of a graphite cathode and an anode operating with constant direct current for the production o...

Determination of mercury in the urine by atomic absorption spectrometry - cold vapor technique

Urine is a liquid waste product of the body. Substances that are ingested and fail to be apsorbed are excreted, solid waste through the intestines, the urine through the kidney and ureter and another fluid from the body through perspiration. Determination of mercury content of urine is not included in routine examinations, but mercury can be present in urine at concentrations that could have se...

Use of Different Gold Amalgamation Techniques in Mercury Determination by Cold Vapor Atomic Absorption Spectrometry

Determination of mercury concentration in the air of dental clinics and the urines of their personnel with cold vapor atomic absorption spectrometry

Background: Dental clinics are known to be one of the largest users of Toxic inorganic mercury. It is well documented that dentists and dental assistants who work with amalgam are chronically exposed to mercury vapor. This study investigates exposure to mercury vapor in a dental clinic. Methods: GBC cold vapor atomic absorption spectrometry (AAS), using sodium borohydride as the reducing age...
