Kotz y Paul M. Bull Chem Soc Jpn. Classification of the Analytical Techniques. Characterization techniques The characterization of synthesized materials was carried out by thermogravimetry, infrared spectroscopy, X-ray diffraction and nitrogen physisorption.

Nuclear magnetic resonance techniques for the study of preferential solvation and the thermodynamics of preferential solvation.

The material ZH shows an X-ray diffraction pattern with incipient signals of very wide bases that are characteristic of materials with poor crystallinity. Abstract This article proposes the High Performance Liquid Chromatography as an alternative to realize the follow up of the weak acids with strong bases titrations.

Material synthesis The synthesis of zirconium hydroxide [Zr OH 4 ] was made by the sol-gel method as previously indicated [20].

Index of preferential solvation was calculated as a function of solvent composition. The aim of this work anaoisis to study the thermal stability that can be induced in zirconium oxide by impregnation of precursor hydroxide with a heteropolyacid, phosphotungstic acid H 3 PW 12 O 40as well as its effect on specific surface area and crystalline structure. Zirconium hydroxide [Zr OH 4 ] was synthesized by the sol-gel lewry using zirconium n-butoxide and 1-butanol as synthesis precursors.

Editorial Kapelusz, Buenos Aires. It was found that before the complete transformation from the tetragonal to the monoclinic structure take place, the crystallite size of pure zirconium oxide was between 4 and 16 nm. Infrared spectroscopy was carried out in a Fourier Transform Spectrometer Perkin-Elmer Spectrum One with transparent wafers containing the sample to be analyzed and KBr as a binder.

The thermograms of Figure 2 corresponding to sample Zr OH 4 -H 3 Lewry 12 O 40show a behavior similar to the thermograms of Zr OH 4instrumebtal a slight shift in temperatures at which the physical and chemical processes previously described occur, which indicates the presence of a different specie in the Zr OH 4.
