Analytical and electroanalytical studies of synthetic composites

Abstract

Composites are 21st century materials used to meet the demand of improved materials and possess a combination of several desirable properties. With time the research conducted on studying more properties and improving the manufacturing process of composite material has increased. Hybrid materials, which consist of organic inorganic materials, are of profound interest owing to their unexpected synergistically derived properties because they can present simultaneously both the properties of an inorganic molecule besides the usual properties of polymer (an organic molecule) with better chemical, mechanical, and thermal stabilities and reproducibility. The composite materials possessing ion-exchange properties have recently drawn particular interest because ion-exchange is important for a variety of applications such as water treatment, chemical separation, and electrochemical sensing indicating its usefulness in environmental applications. The emphasis over industrialization is polluting the natural water day by day by the release of untreated or partially treated water, as well as effluent from sewage treatment plant (that are not performing tertiary treatment) containing toxic compounds into the public sewage or on land. Due to economic as well as good ion-exchange properties composite cation-exchangers will be promising candidates for the removal of heavy toxic metal ions over inorganic ion exchangers or organic resins because of their inherent drawback in terms of chemical and temperature stability, respectively. Aim of the presented work: Attainment of real processibility and applicability of organic-inorganic nano composite cation exchanger in analytical and electroanalytical field is the main aim of the present work. Thus the presented research focussed at exploring the application of polyaniline, polypyrrole and PMMA based synthetic nanocomposites i.e. Polyaniline zirconium titanium phosphate (PANI-ZTP), Polypyrrole zirconium titanium phosphate (PPy-ZTP), Polyaniline zirconium tungstoiodophosphate
