“…Hg 2+ is normally quantitatively analyzed by spectroscopic techniques such as cold vapor atomic absorption spectrometry (AAS) [4], inductively coupled plasma mass spectrometry (ICP-MS) [5], atomic fluorescence spectrometry (AFS) [6], an X-ray fluorescence spectrometry (XRF) [7,8]. Electrochemical techniques such as anodic stripping voltammetry (ASV) [9] are also popular for Hg 2+ detection.…”

“…A number of methods, such as atomic absorption spectrometry (AAS) [2,3], inductively coupled plasma [4], X-ray fluorescence spectrometry [5], anodic stripping voltammetry [6,7] and potentiometry [8,9] have been used for determination of mercury in the analytical samples. Many sensors for potentiometric determination of mercury(II) based on carbon paste CPE [10][11][12][13][14][15][16], polymeric membranes PVC [17][18][19][20][21][22][23][24][25] and coated wire electrodes [26][27][28][29][30] have been reported.…”

A new modified palm shell activated carbon paste electrode based on 1, 4,7,10,8,4,7,10,13-Pentaoxatridecylene)-diquinoline (Kryptofix ® 5) and plasticizing agent was prepared and studied as Hg 2+ selective electrode. The best performance was observed with the electrode composition having the ionophore-palm shell activated carbon-plasticizer composition 10%:50%:40% with Nernstian response over the concentration range of 1.0 × 10 −8 -1.0 × 10 −2 M with a slope of 42 ± 1.5 mV per decade of concentration. The detection limit as determined from the calibration plot is 1.0 × 10 -7 M. The proposed electrode shows good selectivity for Hg(II) with interfering ions. The response time of the electrode is fast (≤10 s), and can be used in the pH range of 3 -11. The electrode was used to determine mercury in drinking water.

“…Many various common methods have been developed for the determination of Hg 2? , such as cold vapor atomic absorption spectrometry (CV-AAS) [4], cold vapor atomic fluorescence spectrometry (CV-AFS) [5], X-ray fluorescence spectrometry [6] and neutron activation analysis [7]. Compared with the above detection methods, however, chemically modified electrodes have received increasing attentions for enhancing the sensitivity and selectivity of electrochemical analysis techniques in the past decades [8].…”

Folding flake-like CuO sub-microstructure was successfully prepared on a large scale using a facile 1, 6-hexanediamin assisted low-temperature solution approach. The growth mechanism of the sample was discussed based on the time-resolved experiments. The experimental results demonstrated that the microstructures of CuO strongly depended on the concentration of the 1, 6-hexanediamin. The as-prepared CuO sub-microstructures were dispersed in Chitosan solution to fabricate composite film on glass carbon electrode. The electrochemical study has shown that the folding flake-like CuO sub-microstructure exhibits highest catalytic effect on Hg 2? than other CuO sub-microstructures. The amperometric response exhibited that the folding flakelike CuO sub-microstructure modified glassy carbon electrode has a good response for Hg 2? with a linear range of 1-200 lM in pH 6.0 phosphate buffered solutions.
