FIELD: measurement equipment.
SUBSTANCE: invention can be used in agriculture, medicine, biology, food and chemical industries. A method for determining content of anions in solutions and moisture-containing products is implemented in an electrochemical cell at passage of alternating current through it. Measurement is carried out at alternating current frequency of 0.1 Hz to 100 kHz. As a measurement parameter, occurrence of phase displacement between e.m.f. and electrical current is used at current passage through the electrochemical cell. Time required for determination is maximum 0.5 minutes.
EFFECT: method is characterised by high measurement accuracy.
