Sažetak
Ion association in aqueous solutions of varied concentrations of LiNO3, NaNO3, Ca(NO3)2, Sr(NO3)2, Ba(NO3)2, Mn(NO3)2, Co(NO3)2, Ni(NO3)2, Cu(NO3)2, Zn(NO3)2 and Cd(NO3)2 was studied by means of UV spectrometry. The formation and the number of spectrally active species in the investigated electrolyte systems were detected by principal component analysis (PCA). The concentrations of associated ion pairs in each solution were determined by means of evolution factor analysis (EFA)1, 2 which also yielded their spectral profiles, ε(). Concentration profiles were used to calculate the ion pairs fractions and their stability constants.
