PROCESS OF DETERMINATION OF IMPURITY CONCENTRATIONS OF REDUCTANTS IN INVESTIGATED MATERIAL WITH USE OF SOLID ELECTROLYTE CELL

摘要

FIELD: analytical instrumentation engineering. SUBSTANCE: content of oxygen and reductants is found with the use of solid electrolyte cell. Fixed constant voltage is applied to cell electrodes. Working chamber sealed in advance is connected to known volume of analyzed water. Water is evaporated and amount of electricity passed through cell for definite period is measured. Impurity concentration is found with allowance for specified amount of electricity and known volume of analyzed water. EFFECT: simplified process, enhanced authenticity of determination. 1 dwg
