Synthesis and characterization of cesium molybdo vanado phosphate immobilized on platelet SBA-15: An efficient inorganic composite ion-exchanger for gadolinium ion sorption

► Immobilization of Cs2H2PMo11VO40 onto platelet mesoporous silica SBA-15 was performed. ► Two-step aqueous impregnation method used for supporting Cs2H2PMo11VO40 onto mesopore. ► Adsorption behavior of sample for gadolinium removal was investigated. ► Adsorption capacity of mesoporous silica by supporting of Cs2H2PMo11VO40 was increased.
