Amino-FeO-functionalized multi-layered graphene oxide as an ecofriendly and highly effective nanoscavenger of the reactive drimaren red.

Amino-functionalized multilayer graphene oxide (Am-nGO) has been synthesized and applied to remove the reactive drimaren red (DR) from aqueous solutions. Infrared spectroscopy evidenced amine and amide presence by peaks at 1579 cm and a band between 3300 and 3500 cm. Raman spectroscopy showed an increment in I/I ratio after amino-FeO-functionalization of nGO from 1.
