Abstrak

Catalytic properties of the nanocluster iron-molybdenum polyoxometalate {Mo72Fe30} in solutions during the oxidation of iodide ions by persulfate have been studied. Automated installation based on spectrophotometric method of analysis controlled by computer was used. Comparison of literary data and kinetic datа on the oxidation of iodide with persulfate showed that keplerate {Mo72Fe30} is a heterogeneous catalyst. These data allowed to assume a non-radical mechanism for persulfate decomposition on the surface of cluster molecules at the first stage of the potassium iodide oxidation reaction. The value of the effective activation energy of the process indicates the catalytic effect of {Mo72Fe30} at the intermediate stage of the decomposition of the hydrogen peroxide.
