Sobre IBD

O presente trabalho tem como foco a remoção de metais pesados (cobre e níquel), na presença de cianeto, de soluções sintéticas e de rales por eletrocoagulação. A experimentação foi realizada utilizando eletrodos de alumínio, pois este material tem se mostrado eficaz para a geração de flocos, além de seu preço acessível no mercado. Foram realizadas análises termodinâmicas, comparando os resultados obtidos com três modelos, os modelos de Langmuir, Freundlich e Temkin, obtendo-se que o modelo que melhor descreve o processo de remoção é o modelo de Langmuir, que sugere que os sítios de adsorção são homogêneos e limitados por uma monocamada, com valores de R2>0,95. Com base nos resultados termodinâmicos, os resultados de , indicam espontaneidade na reação e uma natureza exotérmica do processo de adsorção, sugerindo um mecanismo de fisissorção predominante.
