Trace mercury determination in drinking and natural water samples by room temperature ionic liquid based-preconcentration and flow injection-cold vapor atomic absorption spectrometry

Deter mination of Hg2+ using a glassy carbon electrode modified with [ZnSO4{ZnCl2(u-S-CH2CH2NH2}]n

“…The determination analysis of mercury(II) in water environment is one of the focuses of the scientific research. Several analytical techniques, such as atomic absorption spectrometry [5] , fluorescence spectrometry [6][7][8] , atomic fluorescence spectrometry [9] , quantum dots [10] , nanosensor [11][12][13] , and biosensors [14] have been applied for the determination of the value of mercury(II) in analytical samples. The above mentioned analytical method are preferred for their sensitivity, reproducibility, and easy surface renewal.…”

Fluorescent sensing and determination of mercury (II) ions in water

“…There are existing methods for the determination and detection of Hg 2+ ions, including atomic absorption spectroscopy (AAS) (Martinis et al, 2009), inductively coupled plasma spectroscopy (ICP) (Passariello et al, 1996), molecular absorption spectroscopy (Yang et al, 2010) and electro-analytical techniques (Abu-Shawish, 2009;Khani et al, 2010). While these methods are well established, they often require significant sample preparation and expensive laboratory-based instruments.…”

Visual and On-site Detection of Mercury(II) Ions on Lateral Flow Strips Using DNA-functionalized Gold Nanoparticles

“…4,5 Therefore, it is important to develop a rapid, highly sensitive and selective detection method of Hg 2+ that can provide real-time information of mercury levels in the environment. Towards this goal, different methods for the detection of Hg 2+ have been developed in the past, including cold vapor atomic absorption spectrometry (CVAAS), 6,7 cold vapor atomic fluorescence spectrometry, 8 inductively coupled plasma mass spectrometry (ICP-MS), 9 chromophores, [10][11][12] perylenebisimide fluorophore, [13][14][15] and sensors based on semiconductor quantum dots, 16 proteins 17 and polymer materials. 18,19 New sensors based on chips, 20 single-walled carbon nanotubes 21 and nanoparticles 22,23 have also been applied for the detection of Hg 2+ .…”
