TL;DR: The origin for the superior sorption capability was probed by extended X-ray absorption fine structure (EXAFS) analysis on the uranium-sorbed sample, suggesting multiple amidoxime ligands are able to chelate uranyl(VI) ions, forming a hexagonal bipyramid coordination geometry.
Journal ArticleDOI
Rational design, synthesis, adsorption principles and applications of metal oxide adsorbents: a review.
TL;DR: The basic principles of the adsorption process will be elucidated, including affecting factors, evaluation index, adsorbent mechanisms, and common kinetic and isotherm models, and key parameters affecting the Adsorption performance will be discussed.

Sandia octahedral molecular sieves (soms): structural and property effects of charge-balancing the miv-substituted (m = ti, zr) niobate framework
TL;DR: The temperature of conversion to NaNb(1-x)M(IV)(x)O(3) (M = Ti, Zr) perovskite increased with increasing Ti in the framework and decreased with increasing Zr in the Framework, suggesting that Ti stabilizes the SOMS framework and Zr destabilizes the SomS framework.
