Heterogeneous Fenton-like activity of novel metallosalophen magnetic nanocomposites: significant anchoring group effect.

ABSTRACT: Two new pyridine and thiolate anchoring groups were prepared to functionalize γ-Fe₂O₃ nanoparticles for coordinative attachment of simple Fe(iii)- and Mn(iii)salophen complexes. Four new magnetically recoverable composites were characterized by several analytical techniques such as FT-IR, XRD, TGA, EDS compositional analysis and VSM to confirm superparamagnetic properties. TEM images revealed the nanostructure nature of composites with size ranging between 20 and 40 nm. A heterogeneous advanced oxidation process for degradation of some organic dyes as water pollution compounds using an aqueous solution of H₂O₂ were successfully exploited. Several key parameters including the metal center in the salophen complex, initial pH, catalyst dosage, H
