“…( 2) and ( 4)) were stable up to 60 -70 °C, K S varied in the range from 2 × 10 -8 to 5 × 10 −10 M. The main electrochemical parameters were also determined. They were the linearity ranges of the electrode function (5 × 10 -5 (5 × 10 -6 ) -1 × 10 -2 (1 × 10 -3 ) M) and the slopes of the electrode functions (47 -59 mV decade -1 ), response time (60 -90 s), drift potential (2 -3 mV in a day), shelf life (3 -4 months), limits of detection of tetramethylammonium salts (1 × 10 -5 -4 × 10 -7 M) [71].…”

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.

“…Although various cationic emulsifiers with high corrosion resistance have been developed, the toxic cationic emulsifiers used for preparing the WEP emulsions pose serious threats to human health and natural environments. 13,14 By contrast, the nonionic emulsifiers are more environmentally friendly and exhibit high corrosion r e s i s t a n c e .

Although the environmentally friendly waterborne epoxy (WEP) coatings exhibit high adhesion to substrates, the abundant hydrophilic groups in those coatings always bring about poor anticorrosion performance. Herein, a nonionic WEP emulsifier with the lipophilic–hydrophilic–lipophilic (L-H-L) structure has been successfully prepared to enhance the anticorrosion performance of the WEP coating. After the hydrophilic chains formed between polyethylene glycol (PEG) and hexahydrophthalic anhydride (HHPA) are terminated by epoxy resin (E51), the WEP emulsifier with the L-H-L structure can be obtained, which is then used for preparing the WEP emulsion with regular shape, small particle size, uniform distribution, and high stability by the phase inversion method. The WEP coatings of uniform thickness (110 ± 15 μm) without anticorrosion fillers can be prepared by spraying. The results of electrochemical impedance spectroscopy (EIS) show that the WEP-PEG2000-10% coating exhibits high anticorrosion performance with the low-frequency impedance value as high as 7.47 × 109 ohm·cm2 after being immersed in 3.5 wt % NaCl solution for 60 days. Actually, the L-H-L structure effectively reduces the free hydrophilic groups in the WEP coating, thus significantly improving the anticorrosion performance. This study provides new insight on developing novel inherent WEP coating with high anticorrosion performance.

“…[21] Thus, several potentiometric ion selective sensors have introduced for the determination of cationic surfactant determination up to now. [4,[22][23][24][25][26][27][28] Many surfactant sensors typically consist of a liquid membrane-type sensor, including an ionophore, high molecular weight PVC, and a plasticizer. [29,30] The ionophore serves as the sensing material and is generally responsible for selective interaction with the surfactant counter-ion and for the formation of the ion-pair.…”

“…At this point, because of their remarkable properties, such as high selectivity, broad linear operational range, low limit of detection, high accuracy and precision, short analysis time, simple design, low price, no harm to the measured specimen, no pre‐processing stages, and determination even in colored and sedimentary solutions, potentiometric ion‐selective electrodes/sensors appear as an alternative method to most of the above‐mentioned detection methods for cationic surfactant determination [21] . Thus, several potentiometric ion selective sensors have introduced for the determination of cationic surfactant determination up to now [4,22–28] …”

A potentiometric poly (vinyl chloride) (PVC) membrane cationic surfactant‐selective sensor based on a dodecyltrimethylammonium‐phosphotungstate ion pair as an electroactive material was suggested for the determination of dodecyltrimethylammonium bromide. Membrane optimization studies revealed that the PVC membrane in the composition of 0.5 % dodecyltrimethylammonium‐phosphotungstate ion pair, 69.5 % o‐nitrophenyloctylether and 30.0 % PVC displayed the best potentiometric performance properties. The sensor exhibited a linear response to dodecyltrimethylammonium ions in the concentration range of 1.0×10−6–1.0×10−2 mol L−1 with a detection limit and sensitivity of 5.0×10−7 mol L−1 and 56.6 mV/decade, respectively. The response of the sensor to dodecyltrimethylammonium cation was quite stable, sensitive, selective and rapid (<10 s). The life span of the sensor was found to be about 3 months. The analytical applications of the sensor were successfully carried out with the developed sensor as an indicator electrode for the determination of the end‐point of dodecyltrimethylammonium ions titration and dodecyltrimethylammonium contents of synthetic water samples.
