The objective of
this study was to describe a new and simple method for the determination of
mercury II ions (Hg II) so that it can be used in various routine analyses. A
differential pulse polarographic (DPP) method has been used for the indirect
determination of Hg (II). With a known amount of cyanuric acid (CA) in
polarography cell (BR buffer, pH 10.5) was added an unknown Hg (II) sample and
the Hg (II) concentration is calculated simply from the decrease in the CA peak
after reaction with Hg (II). The linear concentration range was between 20 µM
and 120 µM and limit of detection was calculated to be 6.7 µM. The proposed
method was successfully applied to the determination of Hg (II) in the dried
leave samples belong to C. comosum plant that watered with Hg (II) solution.
The method was extended to the indirect determination of mercury II in C.
comosum plant and results were in agreement with that obtained by a
spectrometric comparison method (ICP-MS). The influences of some other commonly
found inorganic and organic salts on the developed method for the determination
of the trace Hg (II) ions were also investigated. The sufficiently good
recoveries and low standard deviations of the data reflect the high accuracy
and precision of the proposed differential pulse polarographic method.
