Freundlich Adsorption Isotherem
$$ ( \frac{x}{m} ) = Kp^{(\frac {1}{n})} \text{ ; n ≥ 1}$$

Langmuir Adsorption Isotherem
$$ \theta = \frac {KP_{\,A}}{1+KP_{\,A}} $$ $$ or \frac{m}{x} = \frac{aP}{1+bP}$$ $$ or \frac{m}{x} = \frac{1}{aP} + \frac{b}{a}$$


$$ \frac{x}{m} = KC^{(\frac{1}{n})} $$ where C is concentration of solute in solution.

Zeta potential
$$ Z = \frac{4 \pi \eta \mu}{D} $$
