TABLE 1.
Freundlich isotherm results, where equilibrium concentrations of PCE in aqueous solution are relative to the amount of PCE adsorbed to Tenax at different temperatures
| Temp (°C) | K | 1/n | CT (mg g−1) | CLa (mg liter−1) | Concn factorb |
|---|---|---|---|---|---|
| 15 | 14.6 | 0.606 | 50 | 7.6 | 6,580 |
| 25 | 10.9 | 0.631 | 50 | 11.2 | 4,460 |
| 45 | 8.25 | 0.702 | 50 | 13.0 | 3,850 |
| 60 | 8.02 | 0.725 | 50 | 12.5 | 4,000 |
a
CL predicted based on CT and the equation in the text.
b
Equal to CT/CL × 1,000 and gives a relative factor based on a milligram-per-kilogram Tenax or water basis.
