摘要:
Mg/Fe layered double hydroxide loaded with Magnetic(Fe3O4) carbon spheres ([email protected]/Fe-LDHs) was firstly synthesized by a facile in-situ co-precipitation method to remove Pb(II) and Cu(II) pollution. To search the adsorption mechanism, [email protected]/Fe-LDHs was characterized by XRD, FTIR, XPS, TEM, and BET. There may exist surface complexation, precipitation, isomorphic substitution and physical adsorption in [email protected]/Fe-LDHs. The combination of those four types of reactions/interactions of metal ions with composite could ...
