Interaction of Metal Ion‐Coordinated Dipeptide Complex and Ninhydrin in the Alkanediyl‐α,ω‐bis‐Type Gemini Surfactant System

In the current study, interaction of a metal ion‐coordinated dipeptide complex and ninhydrin was examined in the alkanediyl‐α,ω‐bis‐type gemini surfactant system. This work was performed as a function of reactants (ninhydrin and metal‐dipeptide complex), surfactants, temperature, and pH. Different techniques including UV–vis spectrophotometry were used to carry out the experiments. The k ψ –values were evaluated in the presence of alkanediyl‐α,ω‐bis‐type gemini surfactants. A first‐order path in the metal‐dipeptide complex and a fractional‐order path in ninhydrin were noticed. To illustrate the quantitative analysis of k ψ –[gemini] profiles, a pseudophase model of micelles was employed. Thermodynamic parameters were also evaluated and explained. By the observed outcomes, a probable mechanism was suggested and discussed in detail.
