FIELD: chemistry.
SUBSTANCE: electrode-active compound additionally contains pyridine, and copper Cu2+, pyridine and dodecylsulphate are taken in a ratio of 1:2:2 respectively and components of a membrane are in the following ratio, wt %: polyvinylchloride 24.88 - 24.73; dibutylphthalate 74.61 - 74.25; electrode-active compound 0.51 - 1.02.
EFFECT: application of the membrane makes it possible to reduce a limit of ion SAS detection in a water media, reduce errors in the result determination, and reduce the time of electrode response in diluted solutions.
