KINETIC SPECTROPHOTOMETRIC DETERMINATION OF MERCURY IN DIFFERENT MATERIALS BASED ON ITS INHIBITORY EFFECT ON THE BRILLIANT GREEN-SULFITE REACTION
نویسندگان: ثبت نشده
چکیده مقاله:
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

A simple, sensitive and rapid method for determination of trace amounts of nitrite ion in real samples is reported. The reaction is initiated by adding known volumes of a nitrite ion solution of identified concentration to acidic solutions of thionine which causes decolorizaiton of reagent with time. The absorbance changes is then monitored spectrophotometrically at l...
