<br/><br/> This work has been carried out to present and characterize new chemically modified carbon paste electrodes for the determination of three important surfactantsThese surfactants are cetyltrimethylammonium bromide (CTAB) , cetylpyridinium chloride (CPC) and sodium dodecylsulphate (SDS) The electrodes are based on the ion - associations formed from the reaction of the surfactant cation with silicotungstate , silicomolybdate , phosphotungstate and phospomolybdate and dodecylsulphate with the cation of drotaverineThe electrodes were constructed and fully characterized in terms of composition , response time , usable pH range , working concentration range and temperature
