Luffa Cylindrica as a natural adsorbent of cyanide ion in aqueous médium

Cyanide is considered a highly toxic species for any ecosystem in as much as it causes disease in humans, contributes to the loss of soil fertility and contaminates water sources, constituting an important factor in the mortality of aquatic flora and fauna. The aim of this work is to evaluate the po...

The aim of this work is to evaluate the potential ability of the natural sponge Luffa Cylindrica as an adsorbent material to remove cyanide from aqueous medium. In order to measure the adsorption capacity the experiments were carried out through the application of a factorial experimental design that includes variables such as pH and contact time. Suitable conditions to retain the cyanide ion were pH 9.0 and a contact time of 10 minutes.

El presente trabajo evalúa el estropajo (Luffa Cylindrica) como material adsorbente de origen natural para retener ion cianuro en medio acuoso; los ensayos realizados se llevaron a cabo a través de la aplicación de un diseño experimental tipo factorial, evaluando variables como pH y tiempo de contacto en dos niveles. Las condiciones adecuadas para retener el ion cianuro fueron pH de 9,0 y un tiempo de contacto de 10 minutos, el comportamiento adsorbente – adsorbato se representa por la isoterma de Freundlich, el modelo cinético de adsorción se ajusta a pseudo-segundo orden. Se obtuvieron porcentajes de retenciones de ion cianuro que van desde 12.2 hasta 98.0%.application/pdfspaUniversidad Nacional de Colombia (Sede Medellín).
