A theoretical study on the selective adsorption of NH4+ and Cs+ on the phosphomolybdate ion

Add time:08/25/2019    Source:sciencedirect.com

The adsorption mechanisms of NH4+ and Cs+ on phosphomolybdate ion were investigated in detail by density functional theory (DFT). The computational results indicate that [PMo12O40]3− is a cage-like structure formed by the three-membered rings and four-membered rings constructed by the MoO bonds. Both NH4+ and Cs+ could be easily adsorbed at the bridge oxygen site of the four-membered ring on the surface of the [PMo12O40]3− ion. The adsorption of Cs+ on [PMo12O40]3− is more energetically favorable than that of NH4+, which likely accounts for the better Cs+ adsorption capability of ammonium phosphomolybdate.
