Study of Kinetics Incorporation of Ag with TCPP

Authors: Rahmatollah Rahimi, Fariba Moharrami


The Kinetics formation of labile Complex Ag (I) tetra (p-carboxyphenyl) porphyrin, was investigated at 25oC and I=0.1M (NaNO3). By spectrophotometric titration, the composition ratio of the complex was established to be 2:1 (Ag : H2TCPP). The equilibrium constant, K, was found to be log 10-6.53. Binding of the first Ag (I) was found to be rate determining step with rate constant, k1= 4.67×102 . A plausible mechanism is discussed. We discus theoretically why Ag(I)2TCPP is unstable.
