A medium-molecular-weight chitosan was characterized by size exclusion chromatography, viscometry, 1H NMR and UV spectrometry, and its solubilities in aqueous acetic acid and in pressurized CO2-water were determined using a high-pressure view cell coupled to a UV spectrophotometer. The solubility of...

This model allowed us to model dilute chitosan/acetic acid/water systems without the addition of salt with an adequate fit ( R 2 >0.9951) to the trend of the experimental data, enabling the calculation of the pH, degree of ionization, apparent dissociation constant, and the concentrations of ...
Among its therapeutic applications, the following can be emphasized: improvement in the dissolution of drugs with low solubility in water, control of the drug release, improvement of drug targeting, protection against the degradation of the encapsulated compound, and increase of the absorption.37 ...
Chitosan is soluble in the lactic acid and acetic acid. For applying chitosan on muslin cloth it should be in liquid form. Therefore, chitosan solution is prepared by dissolving chitosan 1.4% (w/v) in 2% (w/v) in acetic acid. The solution of standard chitosan and ...
Chitosan is a biopolymer which can provide some ionic conductivity when dissolved in acetic acid. The conductivity is due to the presence of protons from the acetic acid solution. The conducting chitosan film was prepared by the solution cast technique. Several films were prepared and each film ...
in acetic acid at different pH.The biocompatibility of water-soluble chitosan was superior to that of acid-soluble chitosan.Water-soluble chitosan degradated within 7days,while the degradation period of acid-soluble chitosan was longer than 21 days.Conclusions:The results show that the solubility of...
, its solubility reaches about 97% in 1.0% acetic acid under continuous stirring, and the pH was adjusted to 5.6 using 1N NaOH. Triton B as a wetting agent was added at a rate of 0.05% to all spraying solutions before the application. Chitosan was sprayed as a foliar application four ...
This study aims to develop chitosan bioadsorben from shrimp shell waste that is applied to water samples in unlicensed mining activities in the Bone River of Gorontalo Province. The properties of chitosan were characterized, such as the determination of water content, ash content, solubility test ...
