Figure 3. Cyclic voltammograms and ultraviolet–vis spectra of FMN-Na electrolytes.

Figure 3

(a) CVs of 10 mM FMN-Na and 1 M KCl (pH 5.5), 10 mM FMN-Na and 1 M KCl in pH 9.1 buffer (pH 8.6), 10 mM FMN-Na and 1 M KCl in pH 10 buffer (pH 10.0), and 10 mM FMN-Na and 1 M KOH (pH 13.0) aqueous solutions; the dashed CV represents the latter electrolyte after treatment at 363 K for 2 h. (b) CVs of 10 mM FMN-Na 1 M KOH aqueous electrolyte at 10 h intervals over the course of 100 h (sweep rate: 10 mV s−1). (c) Ultraviolet–vis spectra of 50 μM FMN-Na in 1 M KOH aqueous electrolyte 0–6 h after electrolyte preparation.
