Biological Application of Layered Double Hydroxides in Drug Delivery Systems
This review focuses on the extensive study of different layered double hydroxides (LDHs)nanostructures and also their biological and physicochemical (in vitro) properties to encapsulateand deliver drugs with a recognized pharmacokinetic profile in a sustained/modified manner forbetter remedial efficacy contrasted to the corresponding conventional treatments using different<br ...
متن کاملPhotocatalytically Enhanced Cationic Dye Removal with Zn-Al Layered Double Hydroxides
Calcined and organo-modified Zn-Al layered double hydroxides (LDHs) were studied as adsorbents and photocatalysts for removal of cationic dye, as namely methylene blue (MB). Zn-Al LDHs with a cationic ratio of 2:4 were obtained by the coprecipitation method. As-synthesized samples were calcined at different temperatures and the phase transformations were investigated by XRD, TG/DTG, and UV-vis-...
متن کاملAb initio Investigation of Layered Double Hydroxides with Intercalated Herbicides
Layered double hydroxides (LDHs) or hydrotalcite-like compounds exist either as naturally occurring minerals or as synthesized materials by low-cost synthesis methods. LDHs consist of positively charged metal hydroxide layers having the composition [M1–x Mx(OH)2][Ax/m ·nH2O] where M and M are divalent and trivalent cations, respectively. The value of x is the molar fraction and can vary between...
متن کاملSynthesis ratios of Mg-Al and Zn-Al layered double hydroxides efficiency and selectivity in nitrate removal from solution
Four diverse chlorides layered double hydroxides with diverse ratios, i.e. Mg-Al (3:1), Mg-Al (4:1), Zn-Al (4:1), and Zn-Al (3:1) LDHs, were prepared to evaluate their efficiency and selectivity towards nitrate removal from aquatic solutions. A batch experiment was done at the initial nitrate concentration of 5-1000 mg/L, pH 5 to 12, and contact time of 5-180 min. Isotherms of nitrate adsorptio...
متن کاملNomenclature of the hydrotalcite supergroup: natural layered double hydroxides
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 octahedrally coordinated cations for divalent cations, giving a general layer formula [(M 1 xM 3+ x)(OH)2] . This positive charge is balanced by anions which are intercalated between the layers. I...
