Thermal degradation of acetate-intercalated hydroxy double and layered hydroxy salts.
Two hydroxy double salts (HDSs), zinc copper hydroxy acetate (ZCA) and zinc nickel hydroxy acetate (ZNA), and an analogous layered compound, zinc hydroxy acetate (ZHA), have been prepared by a coprecipitation method. The thermal degradation of these materials was characterized via thermogravimetric analysis (TGA), differential thermal analysis (DTA), and TGA coupled with Fourier transform infra...
متن کاملGd(III) complexes intercalated into hydroxy double salts as potential MRI contrast agents.
The ion exchange intercalation of two Gd-based magnetic resonance imaging contrast agents into hydroxy double salts (HDSs) is reported. The presence of Gd(3+) diethylenetriaminepentaacetate and Gd(3+) diethylenetriaminepenta(methylenephosphonate) complexes in the HDS lattice after intercalation was confirmed by microwave plasma-atomic emission spectroscopy. The structural aspects of the HDS-Gd ...
متن کاملCuII Hydroxy Salts: Characterization of Layered Compounds by Vibrational Spectroscopy
Hidroxo-sais lamelares de composição Cu 2 (OH) 3 X (X = NO 3 , CH 3 COO e ClO 4 ) foram sintetizados através da coprecipitação (sais básicos de nitrato e acetato) e da troca iônica (sal básico de perclorato). Os sólidos cristalinos foram caracterizados por difratometria de raios X, análise termogravimétrica e espectroscopia vibracional. Bandas fracas em 336 e 345 cm (espectro Raman) dos sais de...
متن کاملANION EXCHANGE REACTIONS OF LAYERED DOUBLE HYDROXIDES (LDHs) AND LAYERED HYDROXY SALTS (LHSs): QUANTIFICATION OF ION EXCHANGE Abstract Anion exchange reactions of a number of layered double hydroxides with inorganic anions
Anion exchange reactions of a number of layered double hydroxides with inorganic anions were investigated. The five LDH systems used in this study were Mg-Al, Ni-Al, Co-Al, Zn-Al and Zn-Cr. Ni-Zn hydroxynitrate and Ni-Zn hydroxyacetate were the LHSs used in this work. In general, all the LDHs and nickel zinc hydroxysalts exhibited higher extent of exchange towards chloride ions. The extent of e...
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...
