Adsorptive behavior of nanoparticles ZnO was assessed for removal of Sr(II) in aqueous media in the  different trial circumstance such as the effect of parameters (time, pH, concentration of Sr(II) and temperature) on sorption process. The capability of nanoparticles ZnO to remove Sr(II) from aqueous media was followed by a series of adsorption isotherms (Langmuir, Freunlinch and Temkin). The sorption percent and distribution coefficient for nanoparticles ZnO in ideal circumstances are % 96.5 ± 1.76; 6959 mL.g-1 for Sr(II), respectively. According to the Langmuir adsorption model, the maximum adsorption capacity of nanoparticles ZnO for Sr(II) were found to be 1396 mg.g-1 and sorption kinetics was preferable explained by the pseudo-second order equation. Thermodynamic data were identified. The results have been showed that nanoparticles ZnO was appropriate as adsorbent materiel for recovery and sorption of Sr(II) ions from aqueous media. It was found that synthesized ZnO powders had high capacity to recovery Sr(II) of the aqueous media as adsorbent.
