Studies on Ion-Exchange Properties of Polyaniline Zr(IV) Tungstoiodophosphate Nanocomposite Ion Exchanger

Abstract

Organic-inorganic hybrid materials prepared by sol-gel approach have attracted a great deal of attention in material science. Organic polymeric part of the composite provides mechanical and chemical stability whereas the inorganic part supports the ion-exchange behaviour and thermal stability and also increases the electrical conductivity. Such modified composite materials can be applied as an electrochemically switchable ion exchanger for water treatment, especially water softening. Polyaniline zirconium(IV) tungstoiodophosphate nanocomposite ion exchanger is prepared by sol-gel method. Polyaniline zirconium(IV) tungstoiodophosphate nanocomposite ion exchanger is synthesized and characterized by Fourier transform-infrared spectra, ultraviolet-visible spectra, X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, ion exchange, conductivity, and antimicrobial studies. A mechanism for the formation of the polyaniline zirconium(IV) tungstoiodophosphate nanocomposite ion exchanger was discussed. The route reported here may be used for the preparation of other nanocomposite ion exchangers.

Studying the electrical, thermal, and photocatalytic activity of nanocomposite of polypyrrole with the photoadduct of K3[Fe(CN)6] and diethylenetriamine

“…For this purpose many conducting polymer/ inorganic composites have been made which show improved properties compared with those of pure conducting polymers or inorganic materials 2 . The creation of polymer/ inorganic nanocomposites has attracted intensive research owing to their unique physical properties 3 .…”

Use of cellulose acetate–tin (lV) phosphate composite (CA/TPC) in highly effective removal and recovery of heavy metal ions

“…Organic-inorganic hybrid composite materials, due to its exceptional chemical, mechanical and thermal properties as compared to pure inorganic and organic materials, have attracted a great attention in scientific community. Converting the organic and inorganic materials into an organic-inorganic hybrid composite with better properties is an economic method which has been a hot topic [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. The organic-inorganic hybrid composite minimizes the limitations of organic and inorganic materials by modifying individual properties of each of the organic and inorganic materials.…”

Development and Physico-Chemical Characterization of Conducting Polymeric Zirconium Based Advanced Nanocomposite Ion-Exchangers for Environmental Remediation

“…9) of the H + form of PANI/Zr (IV) tungstovanadate composite material shows two major weight losses or degradation portions. The first weight loss region is maximum at around 140°C which is due to the free hydrated water molecules removal [42], while the second gradual loss in the polymer sample weight that began from temperatures above 131 0 C is due to the expel of dopant or interstitial water molecules by condensation of exchangeable hydroxyl groups .This explains that the prepared ion exchanger stable upto 700 0 C.…”
