Новые направления практического применения потенциометрических сенсоров, селективных к анионным и неионным поверхностно-активным веществам

Solid contact tubular and planar potentiometric sensors with PVC membranes containing dodecyl sulfate (DDS) and cationic complex of copper (II) with 1,10-phenanthroline (Phen), planar sensors based on the compounds of polyhydroxyethylated Nonylphenol NF-12 with barium ions and tetraphenylborate (TFB) are developed to determine anionic and non-ionic surfactants. The new fields of application of tubular and planar sensors sensitive to anionic and non-ionic surfactants to the monitoring of anionic SAS in a wide concentration range in wastewater stream, various samples of water of small volume added with sodium alkylsulfates and polyhydroxyethylated compounds, as well as to identification of the surfactants of vegetable origin (nuts, soap tree, medicinal drugs) are presented.
