Titrimetric methods for determining cationic surfactants

Abstract

Aim. To generalize and systematize information on titrimetric methods for determining quaternary ammonium compounds (QACs).Results and discussion. The review summarizes and systematizes information on the properties of surfactants, provides their classification, shows the main ways of use in the national economy, and their role in pharmacy and medicine. Currently known titrimetric methods for determining cationic surfactants (СS), in particular quaternary ammonium compounds, which are widely used in medicine and pharmacy, are described and summarized.Conclusions. As a result of the study, the main directions of developing methods for determining QACs by titrimetry methods have been summarized; the disadvantages and advantages of each of the methods described have been shown. In the future, it can be the basis for developing new and more effective methods of analysis.
