| Abstract: The nanostructured Mg3Si4O10(OH)2 in situ grown on diatomite were first synthesized via a hydrothermal route. Moreover, Mg(OH)2 nanoflowers were first grown on the surface of diatomite after hydrothermal treatment for 0.5~2 h, these nanoflowers obtained the surface areas of 180 m2·g-1. As the hydrothermal reaction time increasing to 3 h, the Mg(OH)2 nanoflowers were completely transformed to lattice-like structure Mg3Si4O10(OH)2 which possessed the higher surface area of 350 m2·g-1. Mg3Si4O10(OH)2/diatomite composite structure showed a well adsorption performance of 570 mg·g-1 for Cr(Ⅵ). It is firmly believed that the adsorbent has a great significance of removing heavy metal ions in wastewater. |
