Anion exchange kinetics of nanodimensional layered metal hydroxides: use of isoconversional analysis.
Anion exchange reactions of nanodimensional layered metal hydroxide compounds are utilized to create materials with targeted physical and chemical properties and also as a means for controlled release of intercalated anions. The kinetics of this important class of reaction are generally characterized by model-based approaches. In this work, a different approach based on isothermal, isoconversio...
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...
