Inorganic complexing agents in the structure of nanoparticles can be used for improve the separation and removal uranium ions from nuclear waste. In this study, the effect of the presence of Schiff base ligand on the structure of silica nanosilica for improve the uranium adsorption was investigated. The results show that modification causes pH of the quantitative adsorption of studied metal ion shifts to the lower pH values. The effect of various parameters such as pH, contact time and amount of adsorbent on the process was investigated. A quantitative removal of the studied metal ions (99.56%) was achieved at pH 4, by 0.05 g of the modified adsorbent disperse in 20 ml of the sample containing the metal ion (20 mgL-1) after 20 min. of magnetically stirring.
