On the Rate of Interaction of Sodium Borohydride with Platinum (IV) Chloride Complexes in Alkaline Media

In this work, sodium borohydride was used as a strong reductant of traces platinum complex ions. The investigations the kinetics redox reaction between platinum(IV) chloride ions and were carried out. For first time, kinetic experiments out in basic medium (pH~13), which prevents NaBH4 from decomposition suppresses release hydrogen to environment. rate constants Pt(IV) reduction Pt(II) under different temperatures concentrations conditions determined. alkaline solution values enthalpy entropy activation are 29.6 kJ/mol –131 J/mol K. It also found that oxygen dissolved strongly affects process. Using collected results, mechanism suggested. appearance diborane an intermediate product during Moreover, influence present reacting on shown.
