“…This reduction mechanism seems to be similar to those already described for other pharmaceutical compounds containing similar carbonyl groups. [18][19][20][21] Furthermore, this peak is strongly pH dependent and it shifts toward more negative potentials by increasing the pH value from 1.0 to 11.0 (ΔE ≅ 0.55 V). From these results, one can conclude that the voltammetric peak obtained at -1.35 V in alkaline medium is related to the same faradaic process that occurs at -0.78 V in acidic medium.…”

“…Detection limits of 35.0 and 180.0 μg L -1 for the amfepramone determination in acidic and alkaline medium, respectively, were calculated from the (3σ) standard deviation (n = 3) of the noise of the equipment and the slope of the calibration function. 21 …”

“…[52][53][54] A matriz mais estudada foi o alimento, principalmente os produtos cárneos curados. Os métodos analíticos destinados para a determinação de N-nitrosaminas em produtos cárneos foram revisados recentemente por Rath e Reyes 55 e Dutra e colaboradores.…”

“…10 We have examined several supporting electrolytes: lithium chloride, sodium chloride, tetraethylammonium chloride (TEAC), tetramethylammonium chloride (TMAC) and tetrabutylammonium iodide (TBAI). TEAC or TBAI were more suitable than the others because of higher solubility and lower background current.…”
