The total ligand concentration (NaF), ionic strength (NaClO<sub>4<\/sub>), and temperature (T = 20-85\u00b0C) is varied, yielding detailed information on the thermodn. of the complexation reaction. Two distinct complex species (NpO<sub>2<\/sub>F<sup>1-n<\/sup>n, n = 1, 2) are identified by peak deconvolution of the absorption spectra. At 20\u00b0C and I<sub>m<\/sub> = 1.0 the absorption band of NpO<sub>2<\/sub>F is located at 983.8 \u00b1 0.2 nm. The absorption band of the NpO<sub>2<\/sub>F<sup>&#8211;<\/sup>2 complex is located at 988.4 \u00b1 0.2 nm. With increasing temperature and ionic strength the chem. equilibrium of the complexation reaction shifts towards the complexed Np(V) species. The conditional stability constants log \u03b2&#8217;<sub>n<\/sub>(T) are calculated according to the law of mass action and are extrapolated to I<sub>m<\/sub> = 0 for each temperature with the specific ion interaction theory (SIT). The determined log \u03b2<sup>0<\/sup>n(T) values increase by 0.2-0.6 in the studied temperature range. Furthermore, the log \u03b2<sup>0<\/sup>n(T) values correlate linearly with the reciprocal temperature and fitting the data according to the integrated Van&#8217;t Hoff equation yields the standard reaction enthalpies (\u0394<sub>r<\/sub>H<sup>0<\/sup>m) and entropies (\u0394<sub>r<\/sub>S<sup>0<\/sup>m).<\/p>\n<p>Applied Geochemistry published new progress about 4551-69-3. 4551-69-3 belongs to pyrazoles-derivatives, auxiliary class Benzenes, name is 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, and the molecular formula is C17H14N2O2, <a href=\"https:\/\/www.ambeed.com\/products\/4551-69-3.html\">Category: pyrazoles-derivatives<\/a>.<\/p>\n<p>Referemce:<br \/><a href=\"https:\/\/en.wikipedia.org\/wiki\/Pyrazole\">https:\/\/en.wikipedia.org\/wiki\/Pyrazole<\/a>,<br \/><a href=\"Pyrazole - Wikipedia\">Pyrazoles &#8211;
