“…Surfactants are organic molecules that contain two components, i.e., hydrophilic (polar) and hydrophobic (nonpolar) parts . These are used all over the world as industrial cleaners, detergents, as an emulsifier, and in cosmetics, etc. , Around 15 million tons of surfactants are produced worldwide every year because of the excessive demand for surfactants . Among the various types of surfactants, anionic surfactants (such as sodium dodecyl sulfate) are the most frequently used .…”

A zirconium(IV)-based metal−organic framework (MOF) fluorophore containing the 2,5-diaminoterephthalic acid (H 2 BDC-(NH) 2 ) linker was synthesized and characterized. The physicochemically stable, porous (S BET = 504 m 2 g −1 ) MOF (1′) exhibited selective and sensitive fluorescence turn-on behavior toward the sodium dodecyl sulfate (SDS) surfactant and turn-off response toward vitamin B 12 . This is the first ever reported MOF-based dual optical sensor of SDS and vitamin B 12 . Other competitive analytes did not interfere in the detection of both the analytes. Along with the lowest ever reported limit of detection (LOD) values (LOD for SDS = 108 nM and LOD for vitamin B 12 = 45.3 nM), 1′ displayed short response time for SDS (50 s) and vitamin B 12 (5 s) detection. The MOF was able to detect SDS in various real water samples and vitamin B 12 in various bio-fluids (urine and serum) and pH media. A MOF-coated cotton composite was fabricated, which displayed a visible color change under UV light even after treating it with a nanomolar concentration of both the analytes. The sensor displayed excellent reusability up to five cycles of sensing. Various experimental outcomes evidenced that the electrostatic interaction between the −NH 2 groups of the linker and the −SO 3 − group of SDS is the possible reason for the selective SDS sensing. For vitamin B 12 , the energy transfer from the probe to vitamin B 12 resulted in fluorescence quenching. In addition, the catalytic performance of 1′ was investigated in the condensation reaction between benzaldehyde derivatives with cyanoacetamide with high yields in ethanol at 70 °C. The solid was used for three cycles with no decrease in its activity and selectivity. PXRD and FESEM analysis before and after the reaction suggested the retention of the crystallinity of 1′, thus indicating catalyst stability.

“…From this point of view, surfactants synthesized from natural and biodegradable materials could be considered as "sustainable" due to their insignificant impact on the environment. 1 Alkyl polyglucosides (APGs) are among "green" and ecofriendly nonionic surfactants and are obtained by the dehydration reaction between glucose hemiacetal hydroxyl and fatty alcohol hydroxyl. They are received from natural materials such as starch and vegetable oil.…”

A phenomenon of supramolecular solvent formation in a micellar solution of alkyl polyglucoside in the presence of primary amine is presented for the first time. Primary amines were investigated as coacervation agents for supramolecular solvent formation based on alkyl polyglucosides (C 8 −C 10 and C 8 −C 14 ). It was found that addition of primary amine promoted in situ formation of tiny supramolecular solvent droplets in alkaline media followed by the separation of a water-immiscible liquid phase. The phenomenon of the formation of supramolecular solvents from an alkyl polyglucoside in an alkaline medium is presented for the first time. The phase diagrams for ternary systems based on alkyl polyglucoside-primary amine-water and physicochemical properties of the supramolecular solvents were investigated. The proposed supramolecular solvents were studied for the microextraction of sulfonamide antibiotics from biological fluids. The salting-out effect on mass-transfer was also investigated. Alkyl polyglucoside C 8 − C 10 and 1-heptylamine provided more effective preconcentration of the antibiotics in the presence of a salting-out agent (sodium carbonate) among studied amphiphiles and coacervation agents. The microextraction procedure was applied to the chromatographic determination of antibiotics in spiked human plasma and serum samples. The limits of detection, calculated from a blank test based on 3σ, were 20 μg L −1 for all analytes.

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.
