:O614.82 文献标志码:A Solid phase extraction of palladium with hexyl benzimidazole sulfide resins HUANG Zhang-jie, CHEN Jing, XIE Ming-jin (School of Chemical Science... with this HBMS. The properties of the extraction of palladium with the HBMS resins were studied. The effects of H+ concentration on the extraction of Pd (Ⅱ) were investigated. The results show that platinum......
at the grain boundaries and precipitated into clusters. Due to the closed-shell electronic configurations of both helium and palladium, Pd grain boundaries yield strong capability of retaining helium atoms.... The diffusion activation energies of interstitial helium atom at these two Pd grain boundaries were also evaluated. Key words: helium atoms; diffusion; grain boundary; palladium; molecular dynamics 1......
