Abstract 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" 1. The method was ...
