(a) Rate of dissolved oxygen decay ($R_{{\mathrm{O}}_2\left(aq\right)}$) at variable initial concentration of PA during λ ≥ 305 nm irradiation of solutions initially saturated with air. The complete experimental conditions can be found in the original work [86]. Adapted from data published in Eugene and Guzman; The Effects of Reactant Concentration and Air Flow Rate in the Consumption of Dissolved O2 during the Photochemistry of Aqueous Pyruvic Acid. Molecules. 2019, 24 (6), 1124; (b) steady-state singlet oxygen production ([¹O₂]_ss) during 1 h irradiation at λ ≥ 305 nm of under continuous and stable saturation with the air of PA solutions. Other experimental conditions can be found in the original work [87]. Copyright 2019, American Chemical Society.
