Synthesis, Ion-Exchange Properties, and Analytical Applications of Anilinium Zirconium(IV) Phosphate

Abstract

A new inorganic ion exchanger, anilinium zirconium(IV) phosphate (AZP), has been prepared under varying conditions. The effects of mixing ratio of reagents and the pH of the mixture on the ion-exchange properties of the material have been studied. The detailed studies, such as ion-exchange capacity, chemical and thermal stabilities, chemical composition, pH titration, and IR analysis were made. Distribution coefficients of metal ions have been studied in water, nitric acid, 1,4-dioxane, aqueous ammonium nitrate, thiourea–nitric acid, and thiourea–hydrochloric acid media. Some analytically important separations of metal ions have been achieved on the small columns of AZP.

Synthesis and Characterization of Organic‐Inorganic Nanocomposite Poly‐o‐anisidine Sn(IV) Arsenophosphate: Its Analytical Applications as Pb(II) Ion‐Selective Membrane Electrode

“…The band at ~1115 cm −1 is attributed to a plane bending vibration of C–H which is formed during protonation of benzene ring. The two peaks at 587 and 540 cm −1 and a peak at 843 indicate the M–O bonding and Sn–O bonding as discussed by D. K. Singh and S. Singh [ 16 ].…”

Synthesis and Characterization of Cerium(IV) Arsenomolybdate Cationic Exchanger

“…After cooling them to room temperature the effect of heating on weight and ion-exchange capacity of the ion-exchanger was examined. The colour of the sample is also found to be affected with the increase in temperature [15]. The results are summarized in Table-3. Chemical stability: Chemical stability of the ion-exchanger was determined by dissolving 0.50 g, of the exchanger in 25 mL of different [16], mineral acids such as HCl, HNO 3 and H 2 SO 4 bases NaOH and KOH and organic solvent such as formic acid of different concentration, with intermittent shaking and kept them as such for 24 h at room temperature and then filtered and finally dried at 40 ± 1 °C in an oven and cooled at room temperature.…”
