Abstract

produção de ácido hipocloroso aquoso através da eletrólise de salmouras modificadas com ph. são divulgados métodos e aparelhos que permitem a produção de soluções aquosas de halogênio com valores de ph controlados. os métodos divulgados incluem a introdução de ácidos em uma salmoura à base de haleto, cuja eletrólise resulta na produção de um produto de solução aquosa de halogênio com um valor de ph desejado, evitando também que o ph do produto atinja um valor indesejado. a tecnologia divulgada também pode utilizar sensores e um sistema de controle utilizando telemetria desses sensores para garantir que a solução aquosa de halogênio desejada seja produzida.
