“…One of the first published examples involving colorimetric methods for determining the kinetics of dye oxidation was the reaction of aqueous solutions of crystal violet and sodium hydroxide (Corsaro, 1964). The reaction of chemical dyes with commercial bleach to form colorless products (neutralizing or altering the dye's normal color) involves common household materials without any exceptional restrictions on handling or disposal.…”

“…These reactions have a long chemical tradition. The rate for the process, in spite of being a cation-anion combination, is slow enough for a conventional kinetic study, and in fact, the reaction has become a popular one for undergraduate laboratories [43]. The reaction also takes place with nucleophiles other than OH − , a fact that has been used for the construction of the familiar Ritchie N + nucleophilicity scale [44].…”

“…Os conceitos básicos associados à análise em fluxo, a sua extensão na combinação da técnica de multi-impulsão com câmara de gradiente, e a sua aplicação a uma reação química permitindo a estimativa de parâmetros cinéticos como a ordem e contante de velocidade, são as principais vantagens do trabalho proposto. Os resultados obtidos para a constante de velocidade estão em boa concordância com os indicados no trabalho do Corsaro 5 . Todavia a metodologia apresentada é mais rápida, reduz o consumo de reagentes e permite a automatização nas medidas melhorando a sincronização da medida da absorvância com a medida do tempo, mitigando, assim, eventuais erros associados ao operador.…”
