Abstract
This present paper reports the synthesis and
environmental applications of conducting polyaniline-Sn(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 Pb2+ 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 Pb2+ ion were found to be 0.97 and 3.24 µg 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.
