چکیده

the complexation reactions of some transition metal ions and 2-aminopyridine (2-ampy) were studied potentiometrically in aqueous solution at µ=0.1 m and 25 °c. the overall stability constants log β’s of all species are obtained by computer refinement of ph-volume data with using the best computer program. several models were tested and the best one accepted according to the least sum of squared deviations. the main species are mhl, ml, ml2, ml3, and ml2(oh)2. for ml complexes the order of stability confirms the irwing-williams series.

Spectrophotometric Study of Complex Formations between Alprazolam and Some Transition Metal Ions in Non Aqueous Solution

In this study, the complexation reaction between Alprazolam (ALP) and metal ions (Zn2+, Ni2+, Cu2+ and Co2+) was investigated by using spectrophotometry in ethanol solvent. The stoichiometry of M+/ALP complexes was calculated by applying the Job, molar ratio and Continuous Changes methods and the relevant diagrams were plotted for each metal ions in each method. The results show that the obtain...
