Layered double hydroxide (LDH) compounds are characterized by structures in which layers with a brucite-like structure carry a net positive charge, usually due to the partial substitution of trivalent...
This study investigates the potential of a Zn/Al layered double hydroxides (LHDs) as an adsorbent for the removal of iodine species from potable water (Theiss et al., 2011b). In this paper the resulta...
卡托普利插层锌铝水滑石的超分子结构、热稳定性及缓释性能研究(Supramolecular Structure, Thermal Property and Sustained-release of Captopril-intercalated Zn/Al-layered Double Hydroxides)
