•Homemade potentiometric screen-printed sensors were developed for determination of homologous sodium alkylsulfates in water samples. The optimization of carbon ink composition was performed.•An ionic associates of sodium dodecylsulfate and cetylpyridinium chloride or cationic complexes of copper (II) with some organic reagents were used as electrode-active compounds of sensors selective to anionic surfactants.•The basic physical and chemical characteristics of tubular and screen-printed surfactant sensors were defined.•Shows high sensitivity and lowest detection limit of sodium alkylsulfates (2.5 × 10−7 M).
New home-made potentiometric screen-printed sensors (SPSs) based on ionic associates of sodium dodecylsulfate (DDS) and cetylpyridinium chloride (CP) or cationic complexes of copper (II) with some organic reagents (N,N′-bis(salicylidene)ethylenediamine (Salen), 1,10-phenanthroline (Phen) and α,α′-dipyridyl (Dipyr)) were developed for the quantitative determination of homologous sodium alkylsulfates in a wide concentration range 5 × 10−7 to 1 × 10−2 (5 × 10−4) M. The low detection limit of homologous sodium alkylsulfates was 2.5 × 10−7 M. The electrochemical behavior and electroanalytical performance of screen-printed and tubular solid-state sensors based on different electrode-active compounds (EAC) were compared. Application to the analysis of water solutions, technical raw preparations, commercial detergents, cosmetic and cleaners is described.
