Synthetic sodalite doped with silver nanoparticles
Abstract
<p>In this work, a novel silver nanoparticles-doped synthetic sodalitic composite was synthesized and characterized using advanced characterization methods, namely TEM-EDS, XRD, SEM, XRF, BET, zeta potential, and particle size analysis. The synthesized nanocomposite was used for the removal of Hg<sup>2+</sup> from 10 ppm aqueous solutions of initial pH equal to 2. The results showed that the sodalitic nanocomposites removed up to 98.65% of Hg<sup>2+</sup>, which is ∼16% and 70% higher than the removal achieved by sodalite and parent coal fly ash, respectively. The findings revealed that the Hg<sup>2+</sup> removal mechanism is a multifaceted mechanism that predominantly involves adsorption, precipitation and Hg-Ag amalgamation. The study of the anions effect (Cl<sup>−</sup>, NO<sub>3</sub><sup>−</sup>, C<sub>2</sub>H<sub>3</sub>O<sub>2</sub><sup>−</sup>, and SO<sub>4</sub><sup>2−</sup>) indicated that the Hg<sup>2+</sup> uptake is comparatively higher when Cl<sup>−</sup> anions co-exist with Hg<sup>2+</sup> in the solution.</p>
