Adsorption of heavy metal ions from wastewater on untreated diatomite was studied. The effect of particle size of the adsorbent (4.76, 3.15 and 2.00 mm) on adsorption efficiency Of Cu2+ Pb2+ and Zn2+, in a ternary, continuous system at constant temperature was investigated. Adsorption capacity was increased with decreasing particle size, and the adsorption order was Cu2+> Pb2+> Zn2+ with the 2.00 mm particle adsorbent.
