Insight of Spectrophotometric Determination Using 4-(2-Pyridylazo)- Resorcinol: Application of Stop Flow Injection Analysis

Metal complexation and its kinetics are very crucial in analytical chemistry for the selective determination of ions of interest. In this study, the kinetics of reactions between 4-(2-pyridylazo)-resorcinol and UO22+, Cu2+ and mixture of UO22++ Cu2+ were examined. The role of pH of solution on the process was evaluated. Spectrophotometric studies revealed the possible existence of cation-cation complexes in solution. Stop flow single flow injection analysis method was used to understand the effect of pH on the stability of the complexes.
