Evolution of novel rGO/ZrHCF composite and utility in electrocatalysis towards nanomolar detection of sodium nitrite and ferulic acid

Voltammetric Investigation of Ferulic Acid at Disposable Pencil Graphite Electrode

“…The results were discussed in correlation with those previously reported in the literature and FA voltammetric behavior was similar with that already described for other working electrodes. The use of the HB_PGE in FA voltammetric quantification by both DPV and SWV presented wide linear concentration ranges of more than three orders of magnitude, which are comparable [20,37,39,42,43,45,47,51,53] or even better than almost all (with four exceptions) [15,[23][24][25][26][27][28][33][34][35][36]38,40,41,44,46,[48][49][50]52,54] voltammetric methods, using modified electrodes reported to date for the FA quantitative determination (Table 4). The LOD values of the voltammetric methods employing the bare PGE for FA detection were similar [25,26,40,41,51,53,54] or even better [27,33,36,38,47,52] than about 1/3 of the 35 papers (Table…”
