Ion exchange resins for gold cyanide extraction containing a piperazine functionality, 1. Synthesis and physico-chemical properties

Adsorption and separation of U(VI) by hafnium phosphate modified with phosphomuscle alcohol

“…In addition, Fig. 4d shows that the N1s characteristic peaks of the HPP-PA-10% sample at the binding energies of 398.5eV and 402.3eV represent C-N-H and C=N + , respectively [24][25][26] , which are consistent with the results obtained from C1s. The characterization of TEM and XPS indicated that PA has successfully introduced into the structure of HfP.…”

Equilibrium and mechanism studies of gold(I) extraction from alkaline aurocyanide solution by using fluorine‐free ionic liquids

“…7b), a new absorption peak appears at 2141 cm −1 and corresponds to the C ≡ N stretching vibration of the aurocyanide complex [22]. The position of the stretching vibration peak of C ≡ N in the IL phase is almost the same as that in the aqueous solution of KAu(CN) 2 and as that in other samples loaded with Au(CN) 2 [33, 34–35]. This result clearly indicates that the coordination environment of gold(I) in the IL phase is little different from that in an aqueous solution.…”

Vertically Oriented BiI3 Template Featured BiI3/Polymer Heterojunction for High Photocurrent and Long-Term Stable Solar Cells

“…It was found that F and N elements, the characteristic elements of Li-TFSI with the characteristic peaks at 688.7 and 399.7 eV, respectively, existed only on the surface of the doped BiI 3 film. 31,32 We infer from this that the BiI 3 /Li-TFSI intermediate phase is not stable and that Li-TFSI remains in the solvent to the last stage of crystallization because of its high solubility in DMF. However, further research is required to determine the specific physical mechanisms of this growth orientation.…”
