Beschreibung
Zusammenfassung:	The invention relates to preparation of a hollow flower-ball-shaped adsorbent based on layered double hydroxides, which is characterized by comprising the following steps of: preparing silicon dioxide (SiO2) under an alkaline condition by taking tetraethyl orthosilicate (TEOS) as a silicon source, and then preparing the adsorbent by taking SiO2 as a substrate and layered double hydroxides (LDHs) as a main component and adopting a hydrothermal method. 一种基于层状双金属氢氧化物的空心花球状吸附剂的制备，其特征在于：以硅酸四乙酯(TEOS)为硅源，在碱性条件下制备出二氧化硅(SiO2)，然后以SiO2为基板，层状双金属氢氧化物(LDHs)为主成分，采用水热法制备吸附剂。
