摘　　要：采用共沉淀法制备镁铝水滑石以及十二烷基苯磺酸钠(SDBS)插层水滑石,应用XRD、FT-IR、TG-DTA等手段表征合成水滑石的结构。实验研究表明:得到的镁铝水滑石(Mg-Al-NO3-LDHs)以及十二烷基苯磺酸钠插层水滑石(SDBS-LDHs)很好地保持了水滑石的层状结构,结构完整,晶相单一。研究表明共沉淀法可以成功地把十二烷基苯磺酸钠插入层状氢氧化镁铝层间,并使用分子动力学模拟方法模拟了插层复合物的微观结构,通过模拟得到的结果与实验测试结果接近。Mg-Al hydrotalcite and sodium dodecyl-benzene sulfonate(SDBS)intercalated hydrotalcite were synthesized by a co-precipitation methods.Powder X-ray diffraction,Fourier transform infrared spectroscopy,and thermal gravimetric-differential thermal analyzer were used in the experimental to characterize the structure of synthesized materials.The experimental data shows that the Mg-Al Hydrotalcite(Mg-Al-NO3-LDHs)and dodecyl sodium benzene sulfonate intercalated hydrotalcite(SDBS-LDHs)well maintain the layered structure of hydrotalcite and have more complete structure and a single crystalline phase.The experiments show that co-precipitation method can be successfully used to insert sodium dodecyl-benzene sulfonate to the interlayer of LDHs.Molecular dynamics simulations is used for simulation of structure of SDBS-LDHs,and the experimental results is close to the conclusions obtained by simulation.
