The experiment was carried out to study the ability of Cu and Zn
adsorption on natural Zeolite using six concentration of Cu and Zn
(50, 100, 150, 200, 250, 300) mg.L-1 and two different diameters
of Zeolite particles (0.5mm-1mm). The research aim
ed to define
the ability of Freundlich and Langmuir isotherms equations.
specifically coefficient R2 was used to determine the suitability of
these isotherms.
