“…On the other hand, in the mixture of R 4 N + and R 3 N the color changed from blue to red-violet in the first endpoint. Therefore, quaternary ammonium compounds and aromatic amines in pharmaceutical preparations can be simultaneously successfully determined by the titration method proposed [62].…”

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.

“…There have been a number of well-established analytical methods for the determination of AS, for instance, biphase titration, 2 high performance liquid chromatography (HPLC), 3 extraction spectrophotometry, 4,5 spectrophotometry in water phase, 6 and fluorimetric methods, 7,8 and so on. Among these methods, titration technique enjoys decent accuracy and precision.…”

The interaction between anionic surfactants (AS) and 1-hexadecyl-3-methylimidazolium bromide [C 16 mim]Br was studied by using resonance light scattering (RLS) technique, UV-Vis spectrophotometry and fluorometric methods. In Britton Robinson (BR) buffer (pH 6.0), [C 16 mim]Br reacted with AS to form supermolecular complex which resulted in enhancement in RLS intensity. Their maximum RLS wavelengths were all at 390 nm. Some important interacting experimental variables, such as the solution acidity, [C 16 mim]Br concentration, salt effect and addition order of the reagents, were investigated and optimized. Under the optimum conditions, quantitative determination ranges were 0.001-7 µg•mL -1 for dodecyl sodium sulfate (SDS), 0.001-6 µg•mL -1 for sodium dodecylbenzene sulfonate (SDBS) and 0.005-7 µg•mL -1 for sodium lauryl sulfonate (SLS), respectively, while the detection limits were 1.3 ng•mL -1 for SDS, 1.0 ng•mL -1 for SDBS and 5.1 ng•mL -1 for SLS, respectively. Based on the ion-association reaction, a highly sensitive, simple and rapid method has been established for the determination of AS.

The project focuses on the efficiency of combined technologies to reduce the release of micropollutants and bacteria into surface waters via sewage treatment plants of different size and via stormwater overflow basins of different types. As a model river in a highly populated catchment area, the river Schussen and, as a control, the river Argen, two tributaries of Lake Constance, Southern Germany, are under investigation in this project. The efficiency of the different cleaning technologies is monitored by a wide range of exposure and effect analyses including chemical and microbiological techniques as well as effect studies ranging from molecules to communities.
