Figure 1

The variation of [H₂O₂] in the reaction mixture (% of the initial concentration) and (insert) negative logarithm of titrated H₂O₂ concentration versus time, from solutions of different initial [H₂O₂] at pH=8.7 for the system (a) PAla-Cu(II), [PAla]=2.0×10⁻³ M, [Cu²⁺]=5.0×10⁻⁴ M. 𝑇=298 K. (b) PGlygly-Cu(II), [PGlygly]=2.0×10⁻³ M, [Cu²⁺]=5.0×10⁻⁴ M. 𝑇=298 K.
