Claims (1)

Образование сульфата натрия в качестве побочного продукта в ходе проведения основанных на серной кислоте процессов получения двуокиси хлора уменьшают, предпочтительнее полностью предотвращают осуществлением электрохимической обработки исходных материалов, содержащих натриевые ионы, для этих процессов с целью удалить натриевые ионы и добавить водородные ионы. В качестве побочного продукта можно получать гидрат окиси натрия. Такой способ в общем применим для электрохимической обработки хлоратов щелочных металлов, сульфатов щелочных металлов и их смесей с получением подкисленных растворов, которые могут быть использованы в качестве содержащих хлоратные ионы исходных материалов для упомянутых процессов производства двуокиси хлора или для других целей.The formation of sodium sulfate as a by-product during the sulfuric acid-based chlorine dioxide production processes is reduced, preferably completely prevented by carrying out electrochemical treatment of raw materials containing sodium ions for these processes in order to remove sodium ions and add hydrogen ions. As a by-product, sodium hydroxide can be obtained. Such a method is generally applicable to the electrochemical treatment of alkali metal chlorates, alkali metal sulfates and their mixtures to produce acidified solutions that can be used as raw materials containing chlorate ions for the chlorine dioxide production processes mentioned or for other purposes.
RU92016631A 1990-06-07 1991-05-23 Method for production of aqueous acidified solution containing chlorate ions, method for electrochemical treatment of aqueous solution of mixture of salts of alkali metals, method for production of chlorine dioxide RU2108413C1 (en)
