Determining Total Mercury in Samples from the Persian Gulf and theCaspian Sea: Comparison of Dry Ash and Wet Extraction Mothods
Monitoring of mercury in environmental samples, with its proven toxicity on the food chain, requires sensitive and accurate analytical techniques. In this study, two methods for identification and quantification of total mercury in biological and sediment samples are compared: i) dry ash preparation and subsequent established procedures for Combustion Atomic Absorption Spectrometry, (AMA 254) ...

SHISHIDO , S. and SUZUKI, T. Mercury in Human Hair: A Comparative Study by Using Two Different Methods of Atomic Absorption and Neutron Activation Analysis. Tohoku J. exp. Med., 1974, 113 (4), 351-356 Magos (1971) reported a new method of atomic absorption spectrometry for selective and simple determination of inorganic and organic mercury. To investigate the reliability of Magos's method, the ...
متن کاملTotal mercury in the hair of children by combustion atomic absorption spectrometry (Comb-AAS).
A simple and rapid procedure for measuring total mercury in human hair was evaluated and compared with a conventional technique. An Advanced Mercury Analyzer (AMA-254) based on sample catalytic combustion, preconcentration by gold amalgamation, thermal desorption, and atomic absorption spectrometry (AAS) (Comb-AAS) was assessed for the direct determination of milligram quantities of human hair....

متن کاملStabilizing Agents for Calibration in the Determination of Mercury Using Solid Sampling Electrothermal Atomic Absorption Spectrometry
Tetramethylene dithiocarbamate (TMDTC), diethyldithiocarbamate (DEDTC), and thiourea were investigated as stabilizing agents for calibration purposes in the determination of mercury using solid sampling electrothermal atomic absorption spectrometry (SS-ETAAS). These agents were used for complexation of mercury in calibration solutions and its thermal stabilization in a solid sampling platform. ...
