In the present work, the  agricultural wastes which are wheat bran and raw okra waste used  as adsorbent material for adsorption  of cadmium and copper ions from wastewater .The effect of adsorption variable which include initial  pH of solution , agitation speed, agitation time, initial concentration of cadmium and copper ions, and amount of adsorbent material were investigated  in a batch process in order to obtain the  maximum  ions removal from wastewater .The results obtained from experimental investigation show that the percentage removal   of metal ions  increases with increasing pH and agitation speed until a maximize value after that it decreased with increasing pH and agitation speed. Also increases with increasing amount of adsorbent material and agitation time until a maximize value then reach a constant value   approximately , and decreasing with increasing  metal ions concentration .The maximum removal percent of cadmium and copper ions were  85.8%  and 52.7 % respectively which obtained at pH equal 5.0, agitation speed 150 revolution per minute, agitation  time 105 minute , metal ion concentration 40mg /L ,and adsorbent amount 1.5gm when using wheat bran as adsorbent material ,while obtained  the maximum removal percent of cadmium and copper ions were  81.7%  and 47.8 % which obtained at pH equal 6.0, and pH equal 5.0 respectively , agitation speed 150 revolution per minute, agitation  time 90 minute ,metal ion concentration 40 mg /L ,and adsorbent amount 1.5gm when using okra waste as adsorbent material. From above result the wheat bran and okra waste was a best adsorbent material for removal cadmium and copper ions from wastewater but wheat bran slightly more effective than okra waste.
