Kinetic Studies and Mechanism of Hydrogen Peroxide Catalytic Decomposition by Cu(II) Complexes with Polyelectrolytes Derived from L-Alanine and Glycylglycine

Figure 2

The variation of [H₂O₂] in the reaction mixture (% of the initial concentration) versus time for different Cu(II) concentrations, and (insert) logarithm of the initial rate (𝑣_𝑜) versus logarithm of the [Cu(II)] for the system (a) PAla-Cu(II), 𝑅=[PAla]/[Cu(II)]=4, initial concentration [H₂O₂]=6.8×10⁻³ M, pH=8.5, 𝑇=298 K. (b) PGlygly-Cu(II), 𝑅=[PGlygly]/[Cu(II)]=4, initial concentration [H₂O₂]=6.2×10⁻³ M, pH=8.9, 𝑇=298 K.
