Cu (II)-Red Onion Skin Extract-Azo metal Complex - A Potential for Oilfield Applications

Red Onion skin extract (ROSE)- azo compound of 2-aminophenol and Cu (II) metal complex of the azo compound (Cu-APmROSE) were formed and characterized using FT-IR spectroscopy, UV-Visible absorption spectroscopy and Scanning electron microscopy. The IR Spectra showed the values of N=N- stretching frequency of 1512.24cm-1 at 1500 cm-1 in APmROSE. This stretching frequency is absent in the Cu-APmROSE. This is an indication of the involvement of the N=N- bond in coordination to the metal. APmROSE shows an absorption maximum at 512 nm. This band was shifted to 334 nm in Cu-APmROSE. This suggests an interaction between the Cu and the azo compound.
