Ion-selective electrodes of the screen printed carbon paste type for the determination of cetylpyridinium chloride, cetyltrimethylammonium bromide, dodecyltrimethylammonium bromide, didodecyldimethylammonium bromide and sodium dodecylsulfate. SPCPEs can successfully be applied in the potentiometric titration of surfactants using the procedures adopted in the application of the ordinary CPE, PVC, CWE, CGE and commercially available electrodes. However, SPCPEs has several advantages of mass production, reproducibility of the preparation process, very simple, sheep and quick preparation process a...
Ion-selective electrodes of the screen printed carbon paste type for the determination of cetylpyridinium chloride, cetyltrimethylammonium bromide, dodecyltrimethylammonium bromide, didodecyldimethylammonium bromide and sodium dodecylsulfate. SPCPEs can successfully be applied in the potentiometric titration of surfactants using the procedures adopted in the application of the ordinary CPE, PVC, CWE, CGE and commercially available electrodes. However, SPCPEs has several advantages of mass production, reproducibility of the preparation process, very simple, sheep and quick preparation process as well as ability for construction of a bielectrode potentiometric strip including both the working and reference electrodes which provide the possibility of measurements on small volumes as well as ability for construction of a portable titration system for field titration of surfactants. The frequently used anionic and cationic surfactants of analytical and technical grads as well as the content of surfactant in different water samples have been successfully titrated and the results agreed with those obtained with commercial electrode and standard two-phase titration method.
