acrylamide [16, 17], whereas the one at 1030 cm<sup>1</sup> reflects on the vibrations of NdCH2 groups. The last peak at 546 cm<sup>1</sup> reflects the FedO functional groups. These functional groups might have participated in the interactions with MB which involved the mechanism of surface complex, hydrogen bonding, and electrostatic attractions.
