摘要：

The properties of chitosan were measured in aqueous acetic acid mixtures at lower concentration of acetic acid. Four chitosan concentrations were prepared in different compositions of acetic acid-water mixtures. Solution densities were measured within uncertainty of ±0.0005 g·cm-3 with a pycnometer and a capillary bore. Data were collected at a frequency of 1 MHz, and the instrument was calibrated with water and benzene. Overall, the results may have importance in industrial areas where chitosan is used as a membrane in pervaporative separation of water-acetic acid mixtures.
