FIELD: industry, analytical instrumentation. SUBSTANCE: for determination of content of ions-impurities in solution with the use of conditivity apparatuses solution is let pass through ion-echange filter and electrodialysis cell. Content of ion-impurities in solution is found by change of electric conductivity of solution ahead of and after electrodialysis cell. EFFECT: enhanced authenticity of determination of content of ions-impurities. 1 dwg, 1 tbl
