摘要: ABSTRACT Several novel crystalline layered zirconium phosphates with composition Zr2O3(HPO4)-nH2O (M=Na, K) were prepared by the partial hydrolytic decomposition of amorphous or a-zirconium in alkaline media under mild hydrothermal conditions. The corresponding Li-and Cs-forms this phosphate obtained successive treatment Na- K-forms LiOH CsOH solutions. Two hydrogen forms (Ψ-ZrP) - Zr2O3(HPO4)-1.5H2O and Zr2O3(HPO4)-0.5H2O acid salt forms. intercalation n-alkylamines into Ψ-ZrP-H from gas phase was also studied. All synthesized materials characterized elemental analysis, TGA, X-ray, IR 31P MAS NMR spectroscopy. data indicate that is a monohydrogen phosphate. It found Ψ-ZrP exhibits unexpectedly extremely high stability media; phosphorus release 1M NaOH being lower than 0.11 -0.13 m...
