ESTRADA, José  e  PUMACHAGUA, Rodolfo. Cigarette nicotine determination applying the second derived technique. Rev. Soc. Quím. Perú [online]. 2007, vol.73, n.2, pp.94-103. ISSN 1810-634X.

In the present work we have evaluated nicotine in tobacco samples corresponding to local cigarette brands by using steam destilation and to later evaluation by derivative spectrophotometry using the second derivative technique. We uses here the extraction method suggested by the Association of Official Analytical Chemists (AOAC).However, for the final analysis and expression of results we have chosen the derivative spectrophotometry because of its simplicity; it doesn' t need to background correction and, its to better accuracy because of the uses of to calibration curves which differs from the conventional spectrophotometric method of determination suggested by the AOAC. The results plows expressed in mg/L and % of total alkaloids and nicotine.

Palavras-chave : nicotine; derivative spectrophotometry; alkaloid.
