Cover Story: This study demonstrates the effectiveness of CoAl-Mo2S12-LDH in removing heavy metal cations from aqueous solutions. The material shows exceptional efficiency, removing over 99.9% of Ag+, Cu2+, Hg2+, and Pb2+ from 10 ppm solutions, with distribution constants as high as 107 mL/g and a remarkable silver cation adsorption capacity of ~918 mg/g. Competitive sorption experiments revealed a selectivity order of Pb2+ ≪ Cu2+ ≪ Hg2+ < Ag+; however, there was limited affinity for harder cations such as Ni2+, Cd2+, and Zn2+, which follows the HSAB rule as sulfur is a soft base. Mechanistic analysis of treated solids through XRD, XPS, and TEM revealed the formation of Ag2S, HgS, and PbMoO4, indicating a precipitation sorption mechanism. View this paper
