Figure 7. Differential pulse voltammetry of 10 mM ibuprofen on an unmodified printed graphite electrode (––) and on a PGE modified with a dispersion of CNTs in chloroform (- -). Inset: 10 mM ibuprofen on PGE. The measurements were carried out in the potential range of 0.6 - 1.6 V, under aerobic conditions, at room temperature (Shumyantseva V.V. et al., manuscript in preparation).
