Abstract:
In this study, a silver nanoparticle decorated polyaniline-nanocrystalline zeolite organic–inorganic hybrid
material was synthesized. The material was characterized by the complementary combination of X-ray
diffraction, N2-adsorption, scanning/transmission electron microscopy, and thermogravimetric analysis.
An electrochemical sensor based on the silver nanoparticle decorated polyaniline-nanocrystalline zeolite
was developed for the nanomolar detection of lindane in an aqueous solution of methanol with high
electro-catalytic activity, stability, sensitivity, and selectivity. The sensor exhibited a wide linear range
from 10 nM to 900 mM with a limit of detection of 5 nM under the optimum conditions. The analytical
performance of the developed sensor was demonstrated for the determination of lindane in different
water bodies with satisfactory recovery.
