Modelling and optimising the performance of graphene oxide-CuSnS-polyaniline nanocomposite as an adsorbent for mercury ion removal.

Finding a cost-effective, efficient, and environmentally friendly technique for the removal of mercury ion (Hg) in water and wastewater can be a challenging task. This paper presents a novel and efficient adsorbent known as the graphene oxide-CuSnS-polyaniline (GO-CTS-PANI) nanocomposite, which was synthesised and utilised to eliminate Hg from water samples. The soft-soft interaction between Hg and sulphur atoms besides chelating interaction between -N and Hg is the main mechanism for Hg adsorption onto the GO-CTS-PANI adsorbent.
