| Summary: | Starting from the favorable analytical properties of -asymmetric dioximes in the
chemical analysis of certain transition metal ions, new methods for quantitative determination of
Pd2+ with aliphatic and alkyl-aryl dioximes were developed. A comparative study was conducted
on the selectivity and sensitivity of the color and precipitation reactions of the analyzed -
asymmetric dioximes, investigating how the nature of the R and R' radicals linked to the dioxime
group influences the physico-chemical properties, on the one hand, of the ligands and the
complexes formed, and, on the other hand, influences their solubilities and gravimetric factors.
The experimental data carried out have highlighted the increased sensitivity and selectivity of
the color reactions of asymmetric α-dioximes with Pd2+ ions. This is why new gravimetric and
spectrophotometric methods have been developed for the determination of these cations in the
form of asymmetric dioximates. |
