Abstract
Poly(o-anisidine) molybdophosphate was expediently obtained by sol-gel mixing of Poly(o-anisidine) into the inorganic matrices of molybdophosphate, which was allowed to react with silver nitrate to the formation of poly(o-anisidine) molybdophosphate embedded silver nano composite. The composite was characterized by Fourier Transform Infrared Spectroscopy, X-ray powder diffraction, UV-Vis Spectrophotometry, Fluorescence Spectroscopy, Scanning Electron Microscopy/Energy-dispersive X-ray Spectroscopy and Thermogravimertic Analysis. Ion exchange capacity and distribution studies were carried out to understand the ion-exchange capabilities of the nano composite. On the basis of highest distribution studies, this nano composite cation exchanger was used as preparation of heavy metal ion selective membrane. Membrane was characterized for its performance as porosity and swelling later on was used for the preparation of membrane electrode for Hg(II), having better linear range, wide working pH range (2–4.5) with fast response in the real environment.
Highlights
Organic-inorganic hybrid materials, based on interactions between organic and inorganic components, have been extensively developed in the past decades [1,2,3,4]
New and novel nano Ag embedded composite material has been synthesized by the incorporation of electrically conducting POMA into the inorganic matrices of MoP, responsible for cation exchange selectivity
Due to the high percentage of yield, better ionexchange capacity, reproducible behavior, chemical and thermal stabilities, best sample was chosen for detail studies
Summary
Organic-inorganic hybrid materials, based on interactions between organic and inorganic components, have been extensively developed in the past decades [1,2,3,4]. We made an attempt to fabricate membranes with metal-incorporated organic-inorganic hybrid material for ion selective electrode, i.e. silver-incorporated Selectivity (Sorption) Studies The distribution coefficient (Kd values) of various metal ions on POMA-MoP/Ag nano-composite were determined by batch method in various solvent systems [25]. Membrane Ion-exchange membrane of POMA-MoP/Ag was prepared as the method reported by A.A. Khan and A.
