摘要：

In this study, two new types of magnetic materials (Fe3O4/EDTA and Fe3O4/PVA) were synthesized. Magnetite (Fe3O4) particles were synthesized by the simple chemical co-precipitation method. After preparation, the magnetite was functionalized with EDTA (Ethylenediaminetetraacetic acid tetrasodium salt dihydrate) and PVA (Polyvinyl alcohol) through a reaction mechanism with complex formation. The resulting sorbents were characterized using FTIR, TGA/DSG and light microscopy. FT-IR spectra revealed that the functionalization of EDTA and PVA on the Fe3O4 surface was successfully performed fact proved by the presence of -COOH peaks. The use of these sorbents to remove manganese from groundwater has been successful, with a removal efficiency of 99%. High efficiency was obtained at a pH 6 at room temperature.
