Abstract
Densities, Ï, and viscosities, η for L-serine, L-threonine, and L-histidine in 0.01 mol·kgâ1 aqueous solutions of hydroxypropyl-β-cyclodextrin have been measured at T = (293.15, 298.15, 303.15 and 308.15) K using DMA 5000 M densimeter and AMVn viscometer. The Ï and η values have been utilized to evaluate values of the apparent molar volume (VÏ), limiting apparent molar volume (VÏ0) and the slope (SV), transfer volume (ÎtrVÏ0), limiting apparent molar expansibilities (ÏE0), hydration number (nH), Falkenhagen coefficient (A) and Jones-Dole coefficient (B) of the systems studied. The results are interpreted in terms of solute-solvent interactions based on a co-sphere overlap model and host-guest interactions.
