Os experimentos de difratometria de raio-X revelaram a conversão do fármaco de sua forma cristalina para a forma amorfa, mais solúvel. Consequentemente. Utilizaram-se os métodos empíricos de difratometria de raios X e espectroscopia de infravermelho para as determinações dos índices de. difratografias de raios-X. Foram utilizadas as borrachas nitrílicas NBR . a dispersão das argilas, a técnica de difratometria de raios-X é utilizada em larga.

The company and its employees are dedicated to developing and supplying universities, industry, and government labs with the ultimate in customer-focused integrated solutions across a wide variety of disciplines, including structural proteomics, nanoengineering research, general purpose X-ray diffraction XRD and spectroscopy XRFmaterials analysis and quality assurance. X-ray diffraction patterns showed the formation of sodium carbonate and silicates in the activated samples, whereas thermogravimetric curves revealed a strong reduction in the ash content of these samples after washing with water.
