a Degradation of RhB under three conditions, UV irradiation, bubble generation, and the combined effect of both. RhB, 2.5 mg/L. b Degradation effects of different volumes of methylene blue. methylene blue, 2 mg/L (30-min reaction time). c, d The impact of air pump-generated bubble interfaces on the degradation of RhB and methylene blue. RhB, 2.5 mg/L (air microbubbles + UV); methylene blue, 5 mg/L (air microbubbles + UV). e Yield of nitrate ion with increasing N2 bubbling time. Error bar for (a–e) are presented as mean values ± SD (n = 3). Source data are provided as a Source Data file.
