Recent trends in kinetics in analytical chemistry and kinetic method for determination of ruthenium (III) using aniline blue-acidic chlorite reaction

摘要

Recent trends in the kinetic rate methods in the past three decades have been concisely reviewed to show the magnanimity of the work and scope of applications in analytical chemistry. Furthermore, based on the highly selective catalytic efficiency of Ru(III) on the oxidation of aniline blue (AB~({thorn})) by acidic chlorite, a fixed-time analytical procedure is described for determination of ultratrace amounts of Ru(III). The attainable lower detection limit is 2.5 ng/ml. The proposed method allows Ru(III) determination with no interference from a wide range of cations, changes in pH, and ionic strength, which is tested with a number of synthetic mixtures
