Resumo
For determination of nonionic surface-active substances (NSAS), in particular, polyoxyethylated nonylphenols, in aqueous solutions, the planar sensors are developed based on various carbon materials (graphite, carbon nanotubes). The effect of the nature and concentration of electroactive compounds (EAC), carbonaceous materials, plasticizers on the electroanalytical and performance characteristics of planar NSAS sensors is observed. It is shown that the planar electrodes can be used in determination of individual homologues of polyoxyethylated nonylphenols in the concentration interval from 1 × 10–5 to 1 × 10–2 М at pH 4–10 in model solutions, in small-volume samples, for determination of the content of surfactants in technological preparations, domestic chemistry products, and also in environmental monitoring of natural waters.
