Abstract

The method of capillary electrophoresis was used to measure the content of aggressive ions in 7 geographical points of the Gelendzhik bay in the air atmosphere and sea water during the period from September 1, 2019 to January 31, 2020. The results of measurements of the contents of K+, Na+, Mg2+, Ca2+, , Cl-, F- are compared with meteorological indicators at the time of measurement. It is shown that the total concentration of cations and anions in sea water corresponds to its salinity measured by the standard method. A high correlation between the chemical composition of samples in air and sea water was revealed.
