Apparent molar volumes and isentropic compressibilities of benzyltrialkylammonium chlorides in water at (293.15, 303.15, 313.15, 323.15, and 333.15)K

Adsorptive removal of cationic surfactants from aqueous solutions onto high-area activated carbon cloth monitored by in situ UV spectroscopy

“…Apparent molar volumes of some of the surfactants in aqueous solutions have recently been reported from this laboratory [47]. It is expected that there might be a correlation between adsorption behaviors of adsorbates and their apparent molar volumes at infinite dilution.…”

Molar Volumes and Refractive Indexes of Hexane-1,2,3,4,5,6-hexol in Aqueous Solutions of 1-Propanol and 2-Propanol

“…The densities of solutions were measured by a quartz vibrating-tube densimeter (Anton Paar DMA 5000) thermostated to better than ± 0.001 K. The precision of the densimeter was ± 2·10 −6 g·cm −3 , which was nearly the same as that of the Anton Paar DSA 5000 vibrating-tube digital densimeter. , This instrument was calibrated with twice-distilled water and dried air. The densities of twice-distilled water we measured were 0.998205 g·cm −3 and 0.997045 g·cm −3 at T = 293.15 K and T = 298.15 K, respectively, which were within the experimental uncertainty of the literature values. , The average of triplicate measurements for each sample was as its final result, and all of the density data are gathered in Table .…”
