Selectivity of cesium from fission radionuclides using resorcinol–formaldehyde and zirconyl-molybdopyrophosphate as ion-exchangers

Sorption behavior of some lanthanides on polyacrylamide stannic molybdophosphate as organic–inorganic composite

“…This sequence is in accordance with the hydrated radii of the exchanged ions. The ions with smaller hydrated radii enter the pores of the exchanger, resulting in higher adsorption [24,25].…”

Determination of ion-exchange kinetic parameters for the poly-o-methoxyaniline Zr(IV) molybdate composite cation-exchanger

“…Hence, research has been motivated to the investigators to have various applications of organic-inorganic composite ion-exchangers in analytical chemistry owing to their better mechanical, chemical, thermal and radiation stabilities, reproducibility and possessing good selectivity for heavy toxic metals [9][10][11][12][13][14][15][16][17][18][19][20], indicating useful environmental applications [21][22][23]. New aapplications of composite materials have been explored in the fields of heterogeneous catalysis [24,25], protective coatings [26], solid polymer electrolyte membrane fuel cells [27,28], ion selective membrane electrodes [23,29], gas perm-selectivity [30,31], ion transport [32,33] and ion exchange [34].…”

Chemical studies on polyaniline titanotungstate and its uses to reduction cesium from solutions and polluted milk

“…Ali (2009) also found the selectivity order; Cs þ > Eu 3þ > Co 2þ onto phosphoric acid activated silico-antimonate, the unhydrated ionic radius was regarded to play a major role affecting on many of these selectivity behavior. The same behavior sequence is similar on resorcinoleformaldehyde (ReF) and zirconyl-molybdopyrophosphate (ZMPP) (Shady, 2009), where the selectivity order on ReF and ZMPP samples is Cs þ > Co 2þ > Eu 3þ > Zn 2þ .…”
