Research on the manufacture and application of nano Fe3O4 materials doped with manganese for treatment of water contaminated with arsenic (III)

Abstract

This article reports results of a reasearch on manufacture and application of nano-Fe₃O₄ materials doped with Mn (Fe₃O₄-x%Mn) for the treatment of water contaminated with As(III). The nanoparticsles were synthesized by chemical method and were studied their size by the XRD and TEM techniques. The experimental results showed that the materials were in crystallized form of cubic face centered structure with particles sizes ranging from 8 to 12 nm. The materials have paramagnetic properties with values of magnetization (Ms) of 53÷65.8 emu/g at room temperature. The best arsenic adsorption property of the materials was observed in water culture with neutral PH levels.
