Background & Objectives: The widespread use of dyes leads to create problems such as environmental pollution in form of color wastewater discharges to environment and also lead to entering of color effluent into receiving waters. The dye lead to prevent of penetration of sunlight into water and thus photosynthetic processes in surface water were disordered. Therefore the aim of this study is determined the efficiency and effectiveness of magnesium oxide nanoparticles in removal of reactive yellow 3 dyestuff from aqueous.

Materials and Methods: This study was experimental that effects of variables affecting on the efficiency of dye removal from synthetic wastewater was studied and survived effect of The parameters: pH(5,7,9), reaction time(30,60,90), adsorbent dose (0.1,0.2,0.3 g) and initial dye concentration(30,50,100,150 mg/l).

Results: The results showed that with increasing contact time, adsorbent concentration and color decreasing, removal efficiency increased, as The most efficiency of dye removal was obtained at Ph= 7(55%), adsorbent amount 0.3 g (96.36%), dye concentration 30 mg/l (86%), and contact time of 90 minute (62.2%).

Conclusion: The efficiency more than 90% prepared absorbent in the removal of dyes from aqueous was shown that it can be used as adsorbent effective in treatment processes. So use this technique to remove colored contaminants from aqueous solutions have been proposed.
