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).
