摘要：

Sulfate intercalated Mg-Al layered double hydroxides (Mg-Al-SO4-LDH) was successfully synthesized by the one step mechanochemical activation method followed by subsequent water washing and aging. Pursuant XRD and FTIR data indicates, product with high purity was obtained after 60 min milling. Results demonstrated that the structural features of Mg-AI-SO4-LDH were affected strongly by milling time (30-900 min) so that interlayer spacing of LDH showed upward trend with some fluctuation. Microscopic analysis showed rounded platelet structure with the average particle size of 50-100 nm. A facile synthesis method was employed and Mg-AI-SO4-LDH was characterized by complementary physical techniques. (C) 2015 Elsevier B.V. All rights reserved.
