溶解在硝基苯中的离子对或凝聚体(由阳离子和阴离子表面活性剂反应形成)可以起到表面活性剂-离子登记装置的作用，对表面活性剂阳离子和阴离子都有反应。十六烷基三甲基溴化铵与十二烷基硫酸钠的络合物、脱氧胆酸钠和鹅去氧胆酸钠的络合物以及气雾剂橙黄T已在硝基苯中用于制备这种有用的液膜。二甲基二十八烷基溴化铵-胆酸钠络合物与十六烷基三甲基溴化铵形成的络合物是水溶性的，用来研究胆酸根离子的行为。液膜的电化学行为被发现是相当好的和可重复性的。用膜电位法测定了表面活性剂在纯态和混合态的临界胶束浓度，以评价后者胶束中表面活性剂与表面活性剂的相互作用。
Ion-pairs or coacervates (formed by the reaction between cationic and anionic surfactants) dissolved in nitrobenzene can behave as surfactant-ion registering devices to respond to both surfactant cation and anion. The complexes of cetyltrimethyl ammonium bromide with sodium dodecyl sulfate, sodium salts of deoxycholic and chenodeoxycholic acids, and Aerosol Orange T have been used in nitrobenzene to generate such useful liquid membranes. The complex of dimethyldioctadecyl ammonium bromide and sodium cholate has been used to study the cholate ion behaviour since its complex with cetyltrimethyl ammonium bromide is water soluble. The electrochemical behaviours of the liquid membranes have been found to be fairly good and reproducible. The membrane potential measurements have been used to determine the critical micelle concentrations of the surfactants in pure as well as in mixed states to evaluate surfactant—surfactant interaction in the micelles of the latter.
