摘要	The selective adsorption by suitable substrate materials is considered one of the most economical methods. In this work, an all inorganic bimetallic Mo-Fe-S cluster is facilely achieved through in situ chemical fixation of tetrathiomolybdate (TTM) on Fe3O4. nanoparticles (NPs) at room temperature (donated as FeMoS NPs). Selective adsorption The bimetallic building blocks on the obtained FeMoS NPs possess a monovacancy species of sulfur, endowing FeMoS NPs with a selectivity order of Zn2+, Mn2+, Ni2+ < Cd2+ << Cu2+ < Pb2+ for metal-ion adsorption, a novel application for the Mo-Fe-S clusters. Particularly, with the highest selectivity for Pb2+ (K-d approximate to 10(7)), which is about 3 x 10(3)-1 X 10(6) times higher than those for other ions and has exceeded that of a series of outstanding sorbents reported for Pb", FeMoS NPs can efficiently reduce the concentration of Pb2+ from, similar to 10 ppm to an extremely low level of similar to 1 ppb. This facile and rational fabrication of the Mo-Fe-S cluster with Fe3O4 represents a feasible approach to cheaply develop novel and efficient materials for the selective removal of lead(II).
