Thermodynamic Modeling of Poorly Complexing Metals in Concentrated Electrolyte Solutions: An X-Ray Absorption and UV-Vis Spectroscopic Study of Ni(II) in the NiCl2-MgCl2-H2O System
Fig 6
Principal component analysis results for NiCl2-H2O and Ni-MgCl2-H2O system in 350–550 nm and 580–850 nm absorbance bands, respectively.
The circle is calculated by 100 ×, where xcalc and xmeas are the model and observed value, respectively. The gray area stands for the level of experimental error of 0.2%-0.5%.
