Determination of Nicotine in Cigarette Tobacco Smuggled to Brazil by Modified QuEChERS Methodology
نویسندگان
چکیده
The study of cigarette authenticity in Brazil is important due to increasing consumption contraband cigarettes. Nicotine concentration an parameter reflecting the quality tobacco used production these Simple methods for this determination, which produce reduced waste, are environmentally and industrially important. nicotine smuggled was determined by QuEChERS method, requiring some modifications, such as decreasing volume extractor solvent, changes pH, removal sample hydration step. Quantification performed gas chromatography using a flame ionization detector. Doehlert matrix design optimize method. extraction recoveries ranged from 97.5% 99.6%, with relative standard deviation (RSD) ≤ 2.5% limits detection quantification 0.6 mg L-1 2.5 L-1, respectively. method sensitive accurate nicotine. cigarettes found be lower than that observed legal successfully applied real samples cigarettes, providing robust routine analysis proving need more studies on control Brazil.

INTRODUCTION Nicotine delivery from smokeless tobacco (ST) products leads to addiction and the use of ST causes pathology that is associated with increased initiation of cigarette smoking. The rapid delivery of nicotine from ST seems to be associated with the pH of the aqueous suspension of the products - high pH is associated with high nicotine absorption. However, early studies compared nicot...
