Background: Mercury in various forms constitute a serious environmental pollutant. Its
exposure is still considered a world related risk for individuals in numerous manufacturers.
The Context and Purpose of the Study: Because of it serious hazardous effects to human health, there
is strong need to develop new tools for mercury ion determination in clinical analysis and environmental
monitoring. This investigation describes for the first time the construction of a polyvinyl chloride
(PVC) membrane electrode which is exceedingly specific to divalent mercury was formed by utilizing
Hg[dimethylglyoxime (phene)]2+ as a suitable carrier.
Results: The sensor exhibits a Nernestian response for mercury ions over a wide concentration range
(5x10-7-5x10-2 molL-1) with a slope of 29±0.5 mV per decade. It has a reaction time of 30s and can be
utilized for 2 months with no quantifiable divergence in potential. The electrode can be used in the pH
range from 1.8-4.5.The average recovery obtained is 91.0% with standard deviation of 1.5% (n=8).
Conclusion: The proposed sensor demonstrates genuinely great segregating capacity towards mercuric
ions in correlation with some heavy metals. This sensor was utilized for the quantitative analysis of
mercuric ions in its aqueous solution. Also, was applied in potentiometric titration as an indicator electrodefor
Hg2+ in various real samples (e.g.; fluorescent mercury lamp white dust, mercurechrome and
