THE SYNERGISTIC INDUCTIVE EFFECT OF METAL -CATIONS ON KINETIC REACTIONS AND ITS ANALYTICAL APPLICATIONS TO THE SIMULTANEOUS DETERMINATION OF MULTICOMPONENTS

The synergistic inductive effect of iron(II) and antimony(III) upon th e chromium(VI)-iodide kinetic reaction systems had been studied, and t he concept of synergistic inductive coefficient was defined, The devia tions from additivity of absorbance within certain concentration range s in previous procedures can be compensated effectively, by introducin g the synergistic coefficient into the simultaneous determination of a binary mixture with stopped flow-FIA method, and the linear concentra tion ranges have also been enlarged remarkably. Iron and antimony cont ents in wastewater, a simulated sample and a zinc standard had been de termined, the results are satisfactory,
