The role of doped-Mn on enhancing arsenic removal by MgAl-LDHs
文献摘要：
To meet the challenges posed by global arsenic water contamination,the MgAlMn-LDHs with extraordinary efficiency of arsenate removal was developed.In order to clarify the en-hancement effect of the doped-Mn on the arsenate removal performance of the LDHs,the cluster models of the MgAlMn-LDHs and MgAl-LDHs were established and calculated by us-ing density functional theory(DFT).The results shown that the doped-Mn can significantly change the electronic structure of the LDHs and improve its chemical activity.Compared with the MgAl-LDHs that without the doped-Mn,the HOMO-LUMO gap was smaller after doping.In addition,the-OH and Al on the laminates were also activated to improve the ad-sorption property of the LDHs.Besides,the doped-Mn existed as a novel active site.On the other hand,the MgAlMn-LDHs with the doped-Mn,the increased of the binding energy,as well as the decreased of the ion exchange energy of interlayer Cl-,making the ability to ar-senate removal had been considerably elevated than the MgAl-LDHs.Furthermore,there is an obvious coordination covalent bond between arsenate and the laminates of the MgAlMn-LDHs that with the doped-Mn.
