In this account, a one-step green hydrothermal method for zirconium-loaded reduced graphene oxide (RGO-Zr) adsorbent was developed in pure water. It is based on the formation of initially strong-coupling RGO-Zr nanocomposites followed by in situ reduction of GO to RGO during the hydrothermal treatment. The phosphate adsorption performance of the as-prepared nanocomposites was investigated in aq...
The self-interstitial atoms (SIAs) mediate the evolution of micro-structures which is crucial in understanding the instabilities of hexagonal close packed (HCP) structures. Taking zirconium as a prototype, we investigate the pressure effect on the stabilities of SIAs using first-principles calculations based on density-functional theory. We found that the pressure greatly affects the stability ...
In the present study, simultaneous gross immobilization of radioactive Cs and Sr in zirconium phosphate was investigated by two methods. “dry method,” a mixture HZr2(PO4)3 with varying amounts CsNO3 Sr(NO3)2 heat-treated at 700 °C for 5 h to prepare + immobilized samples. At 0.3 0.15, leaching 1 mol·dm−3 HCl solution treated 160 24 were 2.9 × 10−4 g·m−2 3.9 g·m−2, respectively. “autoclave aqueo...
