Tow samples of Al2O3/CdO mixed oxide were prepared by co-precipitation method at
PH 8 using concentrated ammonia as precipitated agent.The mixed system was prepared by
mixing aluminum chloride solution with cadmium chloride solution and aluminum ni
trate
solution with cadmium nitrate solution which prepared in previous work.
The nature of anions affected pore radii anions.
The results showed the increasing of micro porosity.
