The origin of ion exchange selectivity in a porous framework titanium silicate Academic Article uri icon


  • The use of in-situ X-ray and neutron diffraction has elucidated the differences in the mechanism of ion exchange between a titanium silicate and a phase in which Nb is substituted for Ti at the 25% level both with the sitinakite structure. The area of interest is the very high level of selectivity required of the exchangers for use in nuclear waste systems. © The Royal Society of Chemistry 2007.
