“…Typically, methylmercury enters the environment either by direct release, through abiotic processes, 1 or via methylation of inorganic mercury in biological systems. 2 This latter process provides an alternative route for the bioaccumulation of methylmercury throughout many food chains.…”

A thermal desorption interface, consisting of a heated, glass-lined splitless-type GC injector, was placed directly at the base of the torch to minimize the length of transfer line. This arrangement provides for fast desorption and high sample introduction ef®ciency. Direct liquid immersion and headspace extraction of methylmercury was studied, including the effect of temperature and time on the extraction ef®ciency. For clean solutions, immersion sampling SPME provided good sensitivity that was linear over two orders of magnitude whereas headspace sampling showed 15% lower sensitivity, but a linear range of more than three orders of magnitude.

“…9 Recently, the SPE cartridges and disks were widely and successfully used for extraction, preconcentration and separation of trace metal ions from different matrixes. [10][11][12][13][14][15][16][17] Several other techniques for the extraction and preconcentration of mercury have been proposed, including, liquid-liquid extraction by reagent 6,18 , preconcentration and precollection by hydride generation/cryogenic trapping 19 , preconcentration by gold amalgam 20 , in situ concentration of mercury vapour in a palladium-coated graphite tube 21 , etc. However, most of these methods are affected by problems, such as the need for large amounts of ligands, reagents and high purity solvents, disposal of organic solvents, long procedures and high cost apparatus.…”

DABTZ as a New Reagent for Solid Phase Extraction and Spectrophotometric Determination of Trace Amount of Hg(II) in Water Sample

2006

Summary -A novel sensitive and simple method for rapid and selective extraction, preconcentration and determination of mercury as its 2,2´ diamino-4,4´ bithiazole (DABTZ) complex by using octadecylsilica cartridges and spectrophotometry is presented. Extraction efficiency and the influence of flow rates of sample solution and eluent, pH, amount of DABTZ, type and least amount of eluent for elution of mercury complex from cartridges, break through volume and limit of detection were evaluated. Also the effects of various cationic and anionic interferences on percent recovery of mercury were studied. Average extraction efficiency >90% was obtained by elution of the cartridge with minimal amount of solvent in the presence of interferences. A preconcentration factor of 152 and a detection limit of 10.92 ng mL -1 were obtained. The method was applied to the recovery and determination of mercury in different water samples.

“…These techniques include spectrophotometry based on dithizone colorimetry, atomic-absorption spectrometry methods, inductively coupled plasma mass spectrometry, hydride generation-atomic fluorescence spectrophotometry and biosensor methods. [27][28][29][30][31][32][33][34][35][36] these methods are usually employed as confirmatory means for the determination of mercury ions. However, they require expensive instruments and professionally skilled technicians.…”
