Parameters of pseudo first- and second-order kinetic models for Pb adsorption by the cattle manure biochar (CM100 and CM400) and bamboo biochar (BB600).
| Biochar | Pseudo first-order model | Pseudo second-order model | ||||
|---|---|---|---|---|---|---|
| Q (mg g−1) | k 1 × 102 (h−1) | R 2 | Q (mg g−1) | k 2 × 102 (g mg−1 h−1) | R 2 | |
| CM100 | 28.2 | 3.39 | 0.98 | 29.2 | 2.88 | 0.97 |
| CM400 | 79.1 | 2.28 | 0.65 | 90.9 | 0.38 | 0.87 |
| BB600 | 50.5 | 3.97 | 0.98 | 56.5 | 0.73 | 0.98 |
The numbers in the sample names represent the pyrolysis temperatures.
