  1. a Q e (mg g−1) is the binding capacity; C e (mg L−1) is equilibrium concentration in the solution; Q max (mg g−1) is the theoretical maximum adsorption amount; K L (L mg−1) is the adsorption equilibrium constant.
  2. b K F is a Freundlich constant related to the adsorption capacity; m is a constant representing the adsorption intensity or surface heterogeneity.
