Aplica??o da espectroscopia no infravermelho e difra??o de raio-X na determina??o de sacarina em ado?antes líquidos artificiais pelo método volumétrico com Ag+DOI: 10.1590/S0100-46702010000400003 Keywords: sweeteners, saccharin, infrared, x-ray. Abstract: the use of sweeteners liquid from saccharin sodium is a public health issue by the relationship with obesity and a source of sodium. the levels of saccharin were studied in four different manufacturers in samples from trade in vitória / es, between years 2006 and 2008. levels were found with values between 260 and 505 above of resolution rdc n0-8, 25/03/2008 from anvisa, which is 0,015 g/100 ml for saccharin and its salts. the profile of the crystallized sweeteners samples were evaluated by infrared spectroscopy and powder x-ray diffraction. the selectivity of the classic method of precipitation with agno3 was also verified by the techniques applied in silver saccharinate precipitates.
