Abstract

The natural zeolite was used as adsorbent for Fe(ІІІ) removal  from aqueous solution. The maximum adsorption capacity was 309.5 mg Fe3+/g zeolite. The kinetic data were fitted to homogeneous micropore model and found that the mass transfer coefficient and diffusivity of the Fe2+ are directly affected by the kinetic parameters.
