KINETIC SPECTROPHOTOMETRIC DETERMINATION OF MERCURY IN DIFFERENT MATERIALS BASED ON ITS INHIBITORY EFFECT ON THE BRILLIANT GREEN-SULFITE REACTION

چکیده
A new kinetic method for the determination of Hg(II) based on its inhibitory
effect on the Brilliant green-sulfite reaction at pH 6.5 is proposed. The reaction
is followed spectrophotometrically at 615 nm by measuring the change in
absorbance at the fixed time of 3.5 min after the initiation of the reaction. Both
the influence of the reaction variables and the interference of many ions have
been studied. Under the selected experimental conditions, Hg(II) was
determined in the range 5.0 - 1300 ng.ml . The method was applied to the
determination of mercury in cleaning solutions for contact lenses and in
industrial waste water
