Abstract

Se proporcionan en el presente documento métodos y composiciones para reducir el nivel de una cianotoxina en el agua contaminada con cianotoxinas. Los métodos de destrucción electrolíticos pueden incluir poner en contacto el agua contaminada con una celda electroquímica en la presencia de una sal de magnesio y aplicar una corriente eléctrica al agua, durante un tiempo y en una cantidad suficiente para oxidar las cianotoxinas. Los métodos son útiles para el tratamiento de agua de lago, agua embalsada, agua de poza, agua de río o agua de irrigación, y cualquier agua que sirva como una fuente de agua potable.
