  1. 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
