“…In the rigid pyranose structure of xylose, any three neighboring hydroxyl groups are not allowed to direct the same side of the structural backbone, making it difficult to form a stable complex with La 3+ . 31,32 Actually, the Morel group showed the significant difference in the thermodynamic parameters in the interaction of a pair of the…”

Xylitol separation from a polyol mixture of the byproducts from bioethanol production processes was performed by liquid chromatography using short columns packed with lanthanide ion-loaded ion-exchange resins. Xylitol was successfully separated with sufficiently high resolution using the adsorbents with medium rare-earth metal ions such as Nd 3+ and Sm 3+ . The adsorbents' specific nature is explained by the so-called "gadolinium break," which is known as a discontinuous behavior of thermodynamic parameters in the complexation of lanthanide series. From the observed behavior, the optimum lanthanide ions could be chosen to prepare the appropriate adsorbents for ligand-exchange chromatography of given polyol mixtures.

“…These characters are favorable in high-throughput analysis and diagnosis. [8][9][10][11] Furthermore, by adding affinity molecules to buffer solution or by constructing a stationary phase in the capillary or microchannel, neutral molecules and enantiomers, which have the same electrophoretic mobility, can be separated due to different interactions between the (pseudo) stationary phase. 12,13 Liu et al immobilized Janus structured Au-Fe3O4 nanoparticles on the capillary and separated dihydroxy benzene isomers.…”
