“…5 Many separation techniques have been proposed to determinate saccharin, such as potentiometry, 6 voltammetry, [7][8][9] spectrophotometry, 10 analysis systems by flow injection [11][12][13] or sequential injection, 14 capillary electrophoresis with UV detection, 15,16 high-performance liquid chromatography with diode array detection (HPLC-DAD), 17,18 and even by classic methods, such as the gravimetry and the titrimetry by Vollhard's method. 19,20 The voltammetric method highlighted among the others cited because it demands a short analysis time, low cost and simplicity. Furthermore, some studies have elucidated the redox process of sodium saccharin by cyclic voltammetry, such as the linear dependence of reduction and oxidation currents and the concentration of sodium saccharin, 7 and the oxidation and reduction current as a function of temperature, 8,21 using, in both, a modified glassy carbon electrode with carbon nanotubes as working electrode.…”
