The kinetic of the reaction of coproporphyrin-I with Zn(II) was spectrophotometrically studied with different metal counter-ions and in the temperature range 25-40°C. The rate constant values depended on counter-ions of Zn(II) and on temperature. The influence of Uv-Vis light on Zn(II)-coproporphyrin-I complex was monitored. The photo-reaction showed a first order kinetic with respect to Zn(II)-coproporphyrin-I complex concentrations with metal liberation and bleaching of solution. The complex was studied and characterized also by fluorescence measurements.

Abstract
The kinetic of the reaction of coproporphyrin-I with Zn(II) was spectrophotometrically studied with different metal counter-ions and in the temperature range 25-40°C. The rate constant values depended on counter-ions of Zn(II) and on temperature. The influence of Uv-Vis light on Zn(II)-coproporphyrin-I complex was monitored. The photo-reaction showed a first order kinetic with respect to Zn(II)-coproporphyrin-I complex concentrations with metal liberation and bleaching of solution. The complex was studied and characterized also by fluorescence measurements.File in questo prodotto:
