“…Sharygin et al first reported PS-ZrO 2 in 1991 [132]. PS-ZrO 2 will serve as a useful alternative to PBD-ZrO 2 for analytes that cannot be resolved on PBD-ZrO 2 because the aromatic functionality of PS-ZrO 2 leads to different selectivity toward aromatic compounds.…”

“…Various procedures for preparing ferrocyanides have been described in the literature: precipitation followed by freeze granulation or drying [1], deposition of thin ferrocyanide films onto the surface of inert (glass, polyethylene terephthalate, Millipore polypropylene membranes) [2][3][4] or sorption-active (clinoptilolite, glauconite) [4][5][6] supports, preparation of composite sorbents consisting of transition metal ferrocyanides and silica gel [7], alumina gel [8], ion-exchange resins [9], or Taunit carbon nanostructured materials [10], and sol-gel method [11].…”

The paper describes how the conditions of preparing ferrocyanides on hydrated titanium dioxide support affect the surface texture of the resulting materials, their elemental and phase composition, and their ability to sorb cesium. The sorbents prepared under the optimal conditions exhibited increases specificity to Cs (K d = 10 5.6±1.0 ml g -1 ) and high capacity (no less than 270 mg g -1 ).Many-year research and the world practice show that mixed transition metal ferrocyanides are the most specific sorbents for cesium radionuclides. Various procedures for preparing ferrocyanides have been described in the literature: precipitation followed by freeze granulation or drying [1], deposition of thin ferrocyanide films onto the surface of inert (glass, polyethylene terephthalate, Millipore polypropylene membranes) [2][3][4] or sorption-active (clinoptilolite, glauconite) [4-6] supports, preparation of composite sorbents consisting of transition metal ferrocyanides and silica gel [7], alumina gel [8], ion-exchange resins [9], or Taunit carbon nanostructured materials [10], and sol-gel method [11].It is noted in practically all the published papers that each synthesis step strongly affects the sorptionkinetic and service characteristics of the sorbents. The properties of the sorbents prepared are determined by the chemical composition, pore structure, and degree of perfection of the sorbent crystal lattice. By varying the pore structure of the material or the chemical nature of the sorbent surface, it is possible to control and improve the sorption properties.It was shown in [2-6] that thin-layer sorbents exhibit the maximally developed surface, the sorption activity that is maximum possible for granulated materials, and good kinetic characteristics; their sorption capacity is utilized to the largest extent. To solve practical problems in radiochemistry and related fields, it is always possible to choose a support for the subsequent preparation of a sorption material exhibiting a set of the required properties. Apparently, the most promising line in the synthesis of new sorption materials is preparation of sorbents by surface modification of sorption-active supports exhibiting highly developed surface. Our studies showed that in this case it is possible to prepare highly specific polyfunctional and complex sorbents. The relationships in formation of the new sorption-active phase, observed in the course of the modification, resemble those observed not only in the growth of thin films on inert supports, but also in the preparation of sorption reagent systems [12].
