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.
