Sorption behaviour of nanocrystalline MOR type zeolite for Th(IV) and Eu(III) removal from aqueous waste by batch treatment

► The BET studies demonstrate the mesoporous character of MOR type materials. ► Sorption of Th(IV) and Eu(III) on analogues of MOR is a favourable and physisorption process. ► Nanocrystalline MOR4 is proved to be good sorbent for both Th(IV) and Eu(III). ► The sorbed metal ions cannot get desorbed by groundwater.
