Abstract

Interest in the polyamic acid-based polymers due to their unique characteristics, by which is possible
to solve problems in the separation and concentration. The most promising in this respect is the study of the
properties of polymers based on polyamide acid. These polymers have a rigid solid structure, optimum
hydrophobic-hydrophilic balance, high thermal stability and selectivity to the singly charged cation. The
paper was studied sorption properties of polymers based on partially imidized polyamic acid. Objects of the
study were selected amino acids (glycine, valine, leucine, methylalanine, glutamic acid), and butyric acid,
propionic acid, oleic acid and palmitic acid. To evaluate the sorption capacity was used modified
piezoelectric sensor. Using the obtained data was built Chart amount of adsorbed substance. The research in
this paper of sorption amino- and carboxylic acids indicated that there is not a clear correlation with sorption
of these compounds to the polymer.
