Oxygen Solubility Enhanced by Fluorinated Materials in Solutiona
Solid | ppm | mM |
---|---|---|
Native silica | 14.9±0.4 | 0.47±0.02 |
Fluorinated silica 6 | 16.7±0.4 | 0.522±0.01 |
Native PVA | 14.9±0.03 | 0.466±0.001 |
Teflon/PVA 8 | 17.9±0.07 | 0.559±0.003 |
Pyrex test tubes contained 5.0 mL of O2–saturated n-butanol with 0.58 g of solid at 25 °C. A pO2 electrode was used to measure the O2 solubility. After removing the solids from solution, the O2 solubility returns to 14.9 ppm (0.466 mM).
