title: A 'build-bottle-around-ship' method to encapsulate ammonium molybdophosphate in zeolite Y. An efficient adsorbent for cesium.
abstract: The faujasite-Y confined ammonium molybdophosphate (AMP-Y) were successfully synthesized for the first time using ammonium molybdophosphate and natural clay from Qaidam Basin as starting materials. The final products were characterized by XRF, XRD, FTIR, (27)Al and (31)P MAS NMR, and N2 adsorption/desorption, which indicated that Qaidam natural clay is a promising low-cost precursor for the production of zeolite Y support. Various loadings of ammonium molybdophosphate could be well encapsulated in the supercage of Y zeolite using a 'build-bottle-around-ship' method. The resultant composite materials were effective for the adsorption of cesium ion from solution.
