Adsorption isotherm models.

Isotherm	Nonlinear	Linear	Parameters
Langmuir	$q_e=\frac{q_{\max }{K}_L{C}_e}{1+K_L{C}_e}$	$\frac{C_e}{q_e}=\frac{1}{K_L{q}_{\max }}+\frac{C_e}{q_{\max }}$	$q_{\max }$: monolayer capacity $K_L$: constant
Freundlich	$q_e=K_F{C}_e^{1/n}$	$\ln q_e=\ln K_F+\frac{1}{n}\ln C_e$	$K_F$: Freundlich constant $n$: adsorption intensity
