Mg/Al layered double hydroxides (LDHs)with nanosized morphology were synthesized by hydrothermal method.The obtained particles and anions intercalation were also characterized by X ray diffraction (XRD)and scanning e-lectron microscopy (SEM).The results showed that the obtained particles are hexagonal with mean diameter of 5 μm and depth of 20 nm,and the morphology of particles are unsteady after various anions intercalation,and the layer space is decrea-sing after intercalation by shorter anions chains:LDH SDBS > LDH NO -3 > LDH S2 O 2-3 .%通过水热合成法,制备了系列层状镁铝双氢氧化物纳米片,并对产物的阴离子插层性能进行了研究和分析.使用 X 射线衍射仪(XRD)、扫描电子显微镜(SEM)等手段对所得样品进行结构检测.结果表明,所得产物为直径约5μm,厚度约20 nm 的六方纳米片.不同阴离子的层间插入对双氢氧化物颗粒形貌有较大影响,层间距随阴离子链长减小而减小：LDH SDBS > LDH NO -3> LDH S2 O 2-3.
