Microporous Framework (Nb, Fe)‐Silicate with Much Potential to Remove Rare‐Earth Elements from Waters

Nanoparticles of a new small‐pore metal silicate formulated as Na(2.9)(Nb(1.55)Fe(0.45))Si(2)O(10) ⋅ xH(2)O and exhibiting the structure of previously reported Rb(2)(Nb(2)O(4))(Si(2)O(6)) ⋅ H(2)O have been synthesized under mild hydrothermal conditions. Replacement of the bulky Rb(+) by smaller Na(+...

description Nanoparticles of a new small‐pore metal silicate formulated as Na(2.9)(Nb(1.55)Fe(0.45))Si(2)O(10) ⋅ xH(2)O and exhibiting the structure of previously reported Rb(2)(Nb(2)O(4))(Si(2)O(6)) ⋅ H(2)O have been synthesized under mild hydrothermal conditions. Replacement of the bulky Rb(+) by smaller Na(+) ions was accomplished by stabilizing the framework structure via partial occupancy of the Nb(5+) sites by Fe(3+) ions. Exploratory ion‐exchange assays evidence the considerable potential of this new silicate to remove rare‐earth elements from aqueous solutions.
