Kinetics and Adsorption Isotherms for the Removal of Tartrazine from Aqueous Solution by Coal Ash
-
M. Ishaq
Abstract
The coal ash (Φ) was used as an adsorbent for the removal of tartrazine from aqueous solution at room temperature. The adsorption capacity of tartrazine increased as the adsorption time was increased and then remains constant after 30 min adsorption duration. It was found that the Φ removed more than 40% of tartrazine from the aqueous solution within 1 h contact time. The equilibrium adsorption was also analyzed by Langmuir isotherm and it was found that the data followed the Langmuir isotherm models.
Kurzfassung
Kohlenasche (Φ) wurde als Adsorptionsmittel zur Entfernung von Tartrazin aus wässriger Lösung bei Raumtemperatur eingesetzt. Die Adsorptionskapazität von Tartrazin nahm zu mit steigender Adsorptionszeit und blieb nach einer Adsorptionsdauer von 30 Minuten konstant. Bei einer Behandlungdauer von einer Stunde konnten mehr als 40% des Tartrazins aus der wässrigen Lösung mit der Kohlenasche entfernt werden. Die Gleichgewichtsadsorption wurde mit Hilfe der Langmuir-Isothermen analysiert. Es wurde festgestellt, dass die Daten der Langmuir-Modellisothermen folgen.
