Q
e
(mg/g) is the amount of dyes adsorbed onto the adsorbent at equilibrium, Q
max
(mg/g) is the maximum amount of adsorption, K
L
(L/mg) is the Langmuir adsorption equilibrium constant, K
F
(mg1–1/n L1/n g−1) is the Freundlich constant representing the adsorption capacity, n (dimensionless) is the constant depicting the adsorption intensity
