Synthesis Of MoS_2-Based Nanohybrid For Effective Removal Of Mercury From Aqueous Solution

摘要

In this study SH-MWCNTs/MoS_2 nanohybrid was synthesized via hydrothermal method. The nanohybrid composite was then characterized using the fourier transform infra-red (FTIR) spectroscopy, scanning electron microscopy (SEM) and Energy-dispersive x-ray spectrometry (EDS) then the successful incorporation of relevant binding groups was confirmed. The synthesized adsorbent was then used for the removal of Hg~(2+) ion from aqueous solution and its adsorption behavior and capacity determine using the kinetic models. It was that Hg~(2+) ion uptake onto SH-MWCNTs/MoS_2 nanohybrid composite occurred through chemisorption mechanism, achieving and adsorption capacity of 0.9661 mg/g. The SH-MWCNTs/MoS_2 nanohybrid nanocomposite therefore showed potential for the removal of Hg~(2+) ion from contaminated water.
