Improvement of magnetite adsorption performance for Pb (II) by
1 Introduction. Magnetite crystallizes in the so-called inverse spinel structure (Space group, Fd3m). The chemical formula is often written as [Fe 3+] A [Fe 3+, Fe 2+] B O 4.This formulation shows that O atoms form a closed-packed cubic lattice, Fe 3+ ions are located in the tetrahedral sites, and a 1:1 mixture of Fe 2+ and Fe 3+ ions fill the …
