Rate constants (k) and half-lives (t1/2) obtained for BaP in the absence of DOSS a.
| BaP b | Lamp Wavelength (nm) | All Lamps Together | ||
|---|---|---|---|---|
| 350 | 419 | 575 | ||
| k (min−1) | (3.79 ± 0.97) × 10−3 | ND c | ND c | (1.12 ± 0.35) × 10−3 |
| t1/2 (min) | 182.9 ± 46.62 | ND c | ND c | 616.4 ± 189.8 |
a All measurements made at the maximum excitation and emission wavelengths of BaP (365 nm/405 nm). b BaP solutions prepared in methanol/water (0.5/99.5; v/v) at a 50 ng·mL−1 concentration. c ND = no photodegradation was observed.
