Schiff's base synthesis has been carried out from the reaction between the compounds 4,4-diaminodiphenyl ether and vanillin. The resulting Schiff base then interacts with Cu2+ metal ions. The characterization of Schiff's base was performed using UV-Visible, FT-IR, XRD spectrophotometers, and pH influence. The interaction between Schiff base and Cu2+ metal ions is studied through the influence o…
