Hydroxy Double Salt Anion Exchange Kinetics: Effects Of Precursor Structure And Anion Size, Everson Kandare, Jeanne Hossenlopp

Chemistry Faculty Research and Publications

H NMR spectroscopy and powder X-ray diffraction have been used to explore the details of anion exchange reactions of two layered hydroxy double salts (HDSs), zinc copper hydroxy acetate (ZCA), nickel zinc hydroxy acetate (NZA), and a related layered material, zinc hydroxy acetate (ZHA), at room temperature (21−22 °C). Reactions that followed Avrami−Erofe'ev kinetics with respect to temporal profiles for acetate release, ZCA with butyrate (k = 1.7 × 10^-3 s^-1), and octanoate (k = 0.79 × 10^-3 s^-1) anions, as well as ZHA with octanoate (k = 2.6 × 10 …
