Structures of the products obtained by anion exchange and reconstruction, and the removal capacities were characterized by XRD, FTIR, UV-Vis and ICP, and the different mechanisms for MgAl-Cl-LDHs and MgAl-LDO were proposed.

• 采用X射线粉末衍射(XRD)、红外光谱(FTIR)、紫外-可见光谱(UV-Vis)和电感耦合等离子体原子发射光谱(ICP)等表征技术,详细探讨了焙烧复原法及离子交换法得到的不同产物的结构和去除S2-性能,提出了MgAl-Cl-LDHs和MgAl-LDO对S2-的不同去除机理。
