Behnajady Department of Chemistry, Tabriz Branch, Islamic Azad University, Tabriz, Iran GR APHICAL A BSTRACT ARTICLE I NFO ABSTRACT Keywords: In this work, Fe O @NiO core-shell nanocomposite was synthesized by precipitation method and various 3 4 Fe O @NiO 3 4 techniques were used to obtain its speciﬁcations. According to TEM images, the average NiO shell thickness was Core-shell nanocomposite about 5 nm and well matched to the crystallite size obtained from XRD. The morphology and purity of the Adsorption nanocomposite were investigated by SEM and EDX techniques, respectively. According to the BET method, the Cr(VI) 2 −1 speciﬁc surface area was equal to 27 m g . The eﬃciency of the synthesized Fe O @NiO nanocomposite to Cr 3 4 Isotherm (VI) removal from aqueous solutions was investigated. The results showed that the Fe O @NiO nanocomposite 3 4 Kinetics could be considered as an eﬀective adsorbent to remove Cr(VI). The eﬀect of parameters such
