Abstract: A kinetic method is described for the determination of mercury(II), based on its catalytic effect on the ligand substitution reaction between hexacynoferrate(II) and Nitroso-R-Salt. The reaction is followed spectrophotometrically by measuring the absorbance at fixed times at 720 nm, the λmax of green coloured complex, [Fe(CN)5NRS]3– formed during the course of reaction under optimum reaction conditions viz, temp = 25.0±0.1 °C, pH = 6.5±0.02 and I = 0.1 M(KNO3). The method is simple, sensitive, selective, rapid and allows the determination of as little as 10–6 M of mercury with good accuracy and precision. The detection limit is computed by standard procedure and found to be 1.6 10–7 M of [Hg2+]. The effects of few interfering and non-interfering cations and anions on mercury(II) determination have also been reported with relative standard deviations.
