Abstract: The effects of Fe(II) concentration, contact time, adsorbent dosage, particle size, temperature and pH on adsorption of Fe(lI) by waste Fe(III)/Cr(III) hydroxide have been studied. The per cent Fe(II) adsorbed increased with decrease in initial concentration of Fe(Il), increase in adsorbent dosage and temperature. The equilibrium data fit well with the Langmuir and Freundlich isotherms. The adsorption rate constants and thermodynamical parameters are presented. Removal of Fe(ll) by the adsorbent is also testified using electroplating industry wastewater.
