| description | The effects of nano zero valent irons on remediation of pollutions from tailing ponds have been investigated in the current study. In order to achieve our goal, the liquid waste of yellow cake production facility was selected as a sample; because in addition to U (40 ppm), this liquid waste contains other elements such as Zn, Cu, Ni, Mn, Na, Ca, S, Si, Al, Mg, P, Cl, Fe and Sr. At first, Lime (C=30%) was used to reduce the concentration of uranium, and lime resulted from concentration of uranium to 0.3 ppm. Finally, we employed uranium concentration as well as NZVI remediated to about 4ppb. The results of these experiments show that at low concentrations of uranium (<5ppm), NZVI has a significant effect in remediation of uranium containing solutions. |
