Synthesis of poly (acrylic acid) modified graphene/MoS2 heterostructure-based composite: an effective removal of Pb(II), Cd(II) and Zn(II) from wastewater

Adsorbent characterization

The surface morphologies of EG, EG/MoS₂, and EG/MoS₂/PAA composite are presented in Fig. 1 below. In Fig. 1(ai-ii), the SEM observation of EG showed the disorderedly stacked EG of diverse sizes and irregular shapes….
