Mechanism of Cu²⁺ Ions Removal from Aqueous Solution with PBTCA Modified Fe⁰ Nanoparticles

Abstract:

Applications of PBTCA modified nanoscale zero valent iron (P-Fe⁰) prepared by borohydride reduction for removal of Cu²⁺ ions from aqueous solution are investigated under a variety of experimental conditions. According to X-ray photoelectron spectroscopy (XPS) results, Cu²⁺ ions were removed primarily via a redox mechanism that resulted in the formation of Cu⁰ and Cu₂O. The contact of P-Fe⁰ with aqueous media caused extensive formation of iron oxide.
