Analysis of Mercury-Rich Plants and Mine Tailings Using the Hydride-Generation AAS Method
A hydride-generation atomic absorption spectroscopy (AAS) method was developed for the analysis of total Hg in liquid matrices of mercury-rich plants and mine tailings samples. The detection limit for this method was as low as 11.4 ng/mL. The reproducibility of the mercury signals (in terms of relative standard deviation) was 4.6%. Accuracy of the method was verified by analyses of deionised wa...

Determination of low selenium concentrations by flow injection hydride generation atomic absorption spectrometry (FI-HG-AAS) - interference by perchloric acid
In routine determinations of selenium (Se) by flow injection hydride generation atomic absorption spectrometry (Fi-HG-AAS) technique a home-made equipment from commercially available components were used. An electrically heated quartz tube was used as atomiser. Blank and Se-standard solutions were analysed after wet digestion using an oxidising acid mixture (HNO3/HClO4). An absorption signal at...
متن کاملdetermination of total mercury and the effects of reducing agent and sample weight on it in canned tuna fish by atomic absorption hydride generation(hg-aas)
on the basis of the some studies recently published on the concentration of potentially dangerous levels of mercury, a global pollutant and highly toxic element in sea fish and specially tuna fish, this work has been carried out to determine the concentration of mercury in canned tuna fish, that compose a large majority of the fish most people eat. for this reason, 30 cans, produced by differen...
متن کاملDetermination of Arsenic in Biological Material by Hydride Generation Atomic Absorption Spectrometry Method
A hydride generation atomic absorption spectrometry method for arsenic determination in biological material was prepared. The samples were digested in muffle furnace at 550oC. The ash was dissolved in 4.5 N hydrochloric acid and the final solution was diluted in 10% hydrochloric acid. The arsenic was determined using a Perkin-Elmer atomic absorption spectrometer equipped with electrodeless disc...
