The Removal of Uranium onto Nanoscale Zero-Valent Iron Particles in Anoxic Batch Systems

Figure 2

(a) Aqueous uranium concentration (ppm) as a function of reaction time (0–672 hrs). The control (nanoparticle-free) solutions (not shown) recorded a variation of <0.01 ppm from the starting concentration in all systems; (b) aqueous iron concentration (ppm) as a function of reaction time (0–672 hrs). The control (nanoparticle-free) solutions (not shown) recorded a variation of <0.02 ppm from the starting concentration in all systems.
