The Study of Complex Formation Between 4-(2-Pyridylazo) Resorcinol and Al3+, Fe3+, Zn2+ and Cd2+ Ions in Aqueous Solution at 0.1M Ionic Strength
Original language description
The complexation reactions between 4-(2-pyridylazo)resorcinol (PAR) and Al3+, Fe3+, Zn2+ and Cd2+ ions at 25oC and 0.1M ionic strength are performed spectrophotometrically. A critical comparison of the various PCA methods on the absorbance matrix data concerning the number of light absorbing species has been made. Knowing of the number of light absorbing species is a critical step for subsequent quantitative and qualitative all solution equilibria studies. Therefore, the nine selected index functions for the prediction of the number of light-absorbing components which contribute to a set of spectra are critically tested using the algorithms implemented in INDICES software. Behind the number of various complexes formed the stability constants of speciesML and MLH type log ?11 and log ?111 for the system of PAR (ligand L) with Zn2+ and Cd2+ ions and the stability constants of species ML, ML2, MLH and ML2H type log ?11, log ?12, log ?111 and log ?121 for the system of PAR (

Czech description
Studium vzniku komplexů mezi 4-(2-Pyridylazo) resorcinolem a Al3+, Fe3+, Zn2+ a Cd2+ ionty ve vodných roztocích a 0.1M iontové síle bylo provedeno spektrofotometricky. Vedle počtu světlo-absorbujících částic programem INDICES byly programem SQUAD a EQUISPEC stanoveny konstanty stability.
