Fit of the release data to kt. The observed values and the fitted values to kt^{n} (a) and Fit of the release data to φ_{o}(1 - exp(-k_{b}t)) (b)^{n} when the pH values of the buffer solution are 4.0, 6.5, and 7.4. The values of the
k and n are (67.215 h^{-1},0.25) for pH 4.0, (35.031 h^{-1}, 0.40) for pH 6.5 and (22.184 h^{-1}, 0.30) for pH 7.4, respectively. For the observed values and the fitted values to
φ_{o}(1 - exp(-k_{b}t)) of the φ_{o} and k_{b}, which lead to the best fits are (100.00, 0.805 h^{-1}), (70.430, 0.659 h^{-1}) and (35.417, 0.605 h^{-1}), respectively, for the three pH values of 4.0, 6.5, and 7.4.
