Preparation of polyaniline based nanocomposite material and their environmental applications

Abstract

This present paper reports the synthesis and environmental applications of conducting polyanilineSn(IV)tungstomolybdate nanocomposite. The material was synthesized via a very simple chemical route and characterized by using various instrumental techniques. Physicochemical properties, pH titrations, and elution behavior were studied to exploit the ion-exchange capability of nanocomposite. Electrical conducting studies were performed by using 4-in-line-probe (Direct Current) electrical conductivity measuring instrument. The conductivity of the material was found to be in the range of semiconductor's. Distribution coefficient values were measured in demineralized water and varying concentration of dimethyl sulfoxide, and on the basis of partition coefficient values, the material was found to be selective for Pb 2? ions. This nanocomposite material has been fruitfully applied for the treatment of heavy metals from synthetic mixture and industrial waste water samples. The limit of detection and the limit of quantification for Pb 2? ion were found to be 0.97 and 3.24 lg L -1 , respectively. The material was also tested for antimicrobial activity, and it was found that besides its use as an ion-exchange material, polyaniline-Sn(IV)tungstomolybdate is successfully used as an antimicrobial agent and as well as semiconductor.

Fabrication of Polyaniline-Zr(IV) Molybdophosphate as a Nanocomposite and its Potential Applications

“…The factors that are involved in the enhancement of conductivity are the presence of the charge carriers and the orientations of polymer chains for electron delocalization [49] in the system. Like other semiconductors, this nanocomposite material follows the Arrhenius model [50]. By varying the percentage of the inorganic precipitate ( Figure S-3) the conductivity increases with a maximum value at 15%, after that there is a decrease (Xu et al 2005; Su and Kuramoto 2000).…”

State of the Art of Synthesized PANI-(Sn+2/TiO2) Nanocomposites for Conductive Application

“…In the same year too, R. Bushra and co-worker introduced the preparation and environmental applications of conducting polyaniline/(Sn +4 ) tungsten molybdate as nanocomposite. [9]. At the same time, according to the study presented by, H. Sun, with research groups, the titanium dioxide/nanoparticles were introduced into poly (ethylene oxide) with silver tetrafluoroborate polymer electrolyte membranes to separation propylene/propane [10].…”
