Thermodynamic data of ion exchange on amorphous titanium(IV) phosphate

Two Independent Routes to Synthesize Identical Silicas by Grafting Ethylenimine or 2-Aminoethanethiol, Their Cation Adsorbing Abilities, and Thermodynamic Data

“…The sequence of adsorption followed should be associated with the volume of hydration (V hyd ) (34) presented by these cations, which are 147.8 for copper and nickel, and 169.6 cm 3 mol −1 for cobalt. The lowest adsorption for cobalt cation should be related to the largest hydration volume, which obstructs the adsorption capacity of the surface and, consequently, causes a decrease in the number of cations adsorbed (32).…”

“…Calorimetry is a suitable technique to obtain information about the interactions of cations with organofunctionalized silicas even though, when this kind of measurement is provided in heterogeneous conditions, the interaction has occurred at a solid/liquid interface of a suspension of the grafted silica gel surface in water (9,27,30,32).…”

Preparation, characterization, and CuX2 and CoX2 (X=Cl−, Br−, ClO−4) adsorption behavior of a polyhedral oligomer silsesquioxane functionalized with an organic base

“…This sequence of adsorption should be associated with the volumes of hydration (V hyd ) [34] presented by these cations, which are 147.8 for copper and 169.6 cm 3 mol −1 for cobalt. The lower adsorption for the cobalt cation should be related to the larger hydration volume, which obstructs the adsorption capacity of the surface, and consequently, causes a decrease in the number of cations adsorbed [34,35].…”

Lead recovery from PbZrO3 using wet ball-mill technique and hydrothermal synthesis of α-zirconium phosphate from wastewater for resource recovery

“…have attracted much attention because of their excellent properties as cation exchangers [6][7][8][9][10][11][12], acid catalyst [13][14][15] and host material for intercalating polar molecules [16]. The crystalline ␣-Zr(HPO 4 ) 2 ·H 2 O was mainly prepared using a pure starting material through two different routs.…”
