Potentiometric determination of anionic surfactants using a new ion-pair-based all-solid-state surfactant sensitive electrode

Use of Plasticizers for Electrochemical Sensors

“…These are very attractive tools due to their good precision, relatively simple manufacturing, relatively low cost and their ability to determine the surfactants in the samples without previous separation steps (Mihali, 2006). The use of surfactant sensitive electrodes with plasticized polymeric membrane for the potentiometric determination of low concentrations of anionic surfactants has been described in several papers (Lizondo-Sabater et al, 2008;Matesic-Puac et. Al, 2005;Mihali et al, 2009;Nemma et al, 2009;Oprea et al 2007 etc.…”

New Potentiometric Sensors Based on Ionic Associates of Sodium Dodecylsulfate and Cationic Complexes of Copper(II) with some Organic Reagents

“…Potentiometry using ion-selective electrodes (sensors) seems a promising modern method of analytical control over the content of anionic surfactants [9][10][11][12][13][14][15]. The potentiometric method provide many advantages as reliability, availability, low cost and simplicity of instrumentation, rapidity, wide concentration range, applicability to colored and turbid solutions, possibility of flow measurement and small solution volumes.…”

“…Ionic associates of dyes, cationic surfactants with anionic surfactants, metalcomplexes, ionic liquids, derivatives of cyclic hydrocarbons are used as electrode-active components (EAC) [7][8][9][10][11][12][13][14][15].

Modelling and optimization of surfactant sensor response characteristics for the use in surface water and wastewater analysis

“…Potentiometry with ion-selective electrodes (ISE) used as sensors is a simple, fast and inexpensive method for determining surfactants and avoids most of the limitations of classical titrimetric methods [3][4][5][6][7][8][9]. Flow-injection analysis was also used for potentiometric determination of anionic surfactants [10][11][12].…”
