Summary of experimental and calculated parameters from the non-linear pseudo 2nd-order kinetic model.
Material Type | qe (expected) (g/kg) | qe (calculated) (g/kg) | K2 | r2 |
---|---|---|---|---|
FM | 8.94 (± 0.1)a | 11.3 (± 5.2)a | 0.015 | > 0.725 |
Activated Carbon | 258 (± 2.0)b | 220 (± 2.5)b | 0.016 | > 0.997 |
CM | 264 (± 1.5)b | 191 (± 7.3)bc | 0.026 | > 0.988 |
Chlorophyll | 198 (± 2.0)c | 168 (± 4.5)c | 0.016 | > 0.964 |
Carbon-chlorophyll | 394 (± 6.0)d | 276 (± 1.5)d | 0.007 | > 0.990 |
CM-chlorophyll | 392 (± 8.0)d | 270 (± 14.0)d | 0.010 | > 0.993 |
qe (expected): experimental adsorption capacity, qe (calculated): model-derived adsorption capacity, K2: pseudo 2nd-order kinetic model rate constant (g/kg-hour), and r2: coefficient of determination. Data is an average of triplicate analyses ± standard error (n = 3). Letters indicate a significant difference between groups in the same column (p ≤ 0.05).
