“…Two oxidation peaks were recorded, which we have designated as O1 and O2. There a number of different theories which have been postulated to explain the voltammetric behaviour of nicotine [32,[38][39][40][41][42]. The majority of reports show nicotine to be oxidised in a single oxidation wave.…”

Third-hand smoke (THS) can be defined as the contamination of surfaces by second-hand smoke.This residue can form further pollutants which can be re-suspended in dust or be re-emitted into the gas phase. THS is a complex mixture and as a result studies have focused on nicotine as a marker of THS, it being the most abundant and indicative organic compound deposited. In this present study, the extraction of dust wipe samples and the subsequent chromatographic conditions required for the separation of nicotine by liquid chromatography with electrochemical detection were investigated and optimised. The optimum chromatographic conditions were identified as a 150 mm x 4.6 mm, 5 µm C 18 column with a mobile phase consisting of 65 % methanol, 35 % pH 8 20 mM phosphate buffer. Hydrodynamic voltammetry was used to optimise the applied potential which was identified to be +1.8 V (vs. stainless steel). Under these conditions, a linear range for nicotine of 13 to 3240 µg/L (0.26 ng -65 ng on column) was obtained, with a detection limit of 3.0 µg/L (0.06 ng on column) based on a signal-to-noise ratio of three. Dust wipe samples were extracted in methanol with the aid of sonication. Mean recoveries of 98.4 % (% CV = 7.8 %) were found for dust wipe samples spiked with 6.50 µg of nicotine. Musk ketone, urea and stearic acid were found not to interfere. Communal entrance ways were found to be contaminated with THS nicotine levels of between 66.8 and 156 µg/m 2 .

“…The LOD was found to be 2.5 × 10 -5 mol·L -1 and the method was applied to a set of refilling liquids for electronic cigarettes (Stočes and Švancara, 2014). Levent et al (2009) described a method for the determination of nicotine using pencil graphite electrode in the presence of anionic surfactant with LOD of 2.0 × 10 -6 mol·L -1 . In recent years, several electrochemical biosensors were constructed for determination of nicotine (Campanella et al, 2001;Highton et al, 2009).…”

A novel protocol for the simple and rapid determination of nicotine using square-wave voltammetry at boron-doped diamond electrode was developed. The effect of pH of supporting electrolyte, scan rate and square-wave voltammetric parameters was examined. Behavior study revealed that nicotine provided two irreversible oxidation peaks, the first one well-shaped at +1.14 V and the second one poorly-defined at +1.61 V vs. Ag/AgCl electrode in the presence of phosphate buffer (pH 9.0). Under optimal experimental conditions (modulation amplitude of 40 mV, frequency of 50 Hz and scan rate of 0.225 V·s -1 ), the current response of nicotine was proportionally linear in the concentration range from 9.9 × 10 -6 to 1.7 × 10 -4 mol·L -1 (R 2 = 0.996) with the detection limit of 6.1 × 10 -6 mol·L -1 (0.989 mg·L -1) and the relative standard deviation of 8.8 % (number of measurements n = 10, 5.7 × 10 -5 mol·L -1 nicotine). The proposed procedure was applied to the quantification of nicotine in cigarettes and chewing gums with the determined values in good agreement with those declared by producer. In this respect, the developed protocol could represent an effective and rapid alternative to chemically modified electrodes in analysis of alkaloids.

“…The frequent intake of nicotine leads to many potential effects on human health such as increased blood pressure and heart beat, atherosclerosis of the respiratory organs, and stimulation of the central nervous system leading to disruption of arteries and cardiovascular risk factors [8,9]. Smoking contributes heavily to the mortality burden because it is a major cause of vascular disease, cancer and chronic obstructive pulmonary disease [10].…”

ABSTRACT. The electrochemical behavior of nicotine was investigated using cyclic and square wave voltammetric techniques. Electrochemical activation of glassy carbon electrode significantly increased the oxidation peak current of nicotine compared to the bare glassy carbon. At the activated glassy carbon electrode, the square wave voltammetry of nicotine revealed an oxidation peak at +838 mV (vs. SCE) in phosphate buffer solution of pH 7. Under optimized conditions, the linear range (R 2 = 0.998) and detection limit (3σ) for nicotine determination were found to be 1-200 µM and 0.7 µM, respectively. The method was successfully applied for the determination of nicotine in two brands of commercial cigarettes and acceptable recovery values of 97-108% were found.
