Silver nanoparticle decorated polyaniline–zeolite nanocomposite material based non-enzymatic electrochemical sensor for nanomolar detection of lindane

Author affiliations

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 μM 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.
