摘要：Remediation of wastewater contaminated with Cr(VI) species by ceria particles has received considerable attention in recent years. The main objectives of the present study were to investigate the adsorption of Cr(VI) species on the one-dimensional (1-D) ceria nanorod (CeNR). In where, CeNR has 20–40 nm in diameter and 200–300 nm in length, as confirmed through FE-SEM and TEM images. Higher surface area of CeNR is insisted to the remediation of Cr(VI)-contaminated wastewaters. This work exemplifies the utilization of XAS and BET to reveal the speciation of CeNR for further understands of the very complex adsorption process. It is also very clear that decontamination of Cr species in wastewater via the in-situ remediation with CeNR permeable reactive barriers would be environmentally attractive in the near future.
