موضوع به انگلیسی:Synthesis and the formation analysis of Ni (II), Zn (II) and L-glutamine
binary complexes in dimethylformamide-aqueous mixture
بخشی از متن:The convergence analysis of Ni (II) and Zn (II) and L- Glutamine complexes were studied using (0–50% v/v)
dimethylformamide (DMF)-water mixtures potentiometrically at temperature 301.0 K, having an ionic strength
of 0.15 mol L 1. The complex species models were analysed by a well-defined computer Programme MINIQUAD75.
Exhaustive modeling have been carried out on a number of complex species. The main complex species
formed have been found of NiL2, NiL2H, NiL2H2, ZnL2, ZnL2H and ZnL2H2 type. On the basis of the statistical
parameters the best fit chemical modelling have been applied. The statistical data analysis validated the complex
species. The occurrence of columbic interactions over non-columbic interactions have been identified by linear
variation stability of the medium with the help of mole fraction, and the preference of non-columbic interactions
over columbic interactions as per linear variation of stability are because of dielectric constants of the medium.
