“…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] …”
