The electrooxidation of l-dopa at GC electrode was studied by in situ UV-vis spectroelectrochemistry (SEC) and cyclic voltammetry. The mechanism of electrooxidation and some reaction parameters were obtained. The results showed that the whole electrooxidation reaction of l-dopa at glassy carbon (GC) electrode was an irreversible electrochemical process followed by a chemical reaction in neutral solution (EC mechanism). The spectroelectrochemical data were treated by the double logarithm method together with nonlinear regression, from which the formal potential E 0 228 mV, the apparent electron-transfer number of the electrooxidation reaction an 0.376 (R 0.99, SD 0.26), the standard electrochemical rate constant k 0 (3.93 AE 0.12) Â 10 À 4 cm s À 1 (SD 1.02 Â 10À 2 ), and the formation equilibrium constant of the following chemical reaction k c (5.38 AE 0.34) Â 10 À 1 s À 1 (SD 1.02 Â 10À 2 ) were also obtained.

“…In a thin layer cell the Nernst equation expressed by absorbance is obtained as E ¼ E 0 +RT=nF* Ln((De i 7 De 0 )= (De 1 ÀDe i )) [29], where De 0 , De 1 and De i are the CD absorbance intensity at initial, final and at an intermediate applied potential step, respectively. The formal potential (E 0 ¼ À0.387 V) and electron transfer number (n ¼ 1.71 % 2.)…”

“…In situ visible region spectroelectrochemistry [1][2][3][4] has traditionally been used for the characterisation of the colour states of electrochromic materials [5][6][7][8][9]. However, although a visible region spectrum gives an objective measure of colour absorption, it provides little insight into the impact on the human eye of the subjective perception of hue, saturation and relative luminance.…”
