The use of low-cost activated carbon derived from reed, an agricultured waste material,
has been investigated for the removed of Fe (II) from wastewater, using batch method. The
influences of the weight of adsorbent (0.2-2) g, pH of solution (1-9) and initial Fe(II)
concentration (10-80) mg/l have been studied. The suitability of the activated carbon used
was tested by fitting the adsorption data with Langmuir and Freundlich isotherms. The
study showed that the adsorption data obtained are obey the Freundlich isotherm fitting.
