Using natural adsorbants for the removal of dyes from solutions may represent a new and effective method of dye control and treatment. In this study, the adsorption of methyl orange by Lebanese Eryngiumcreticum was evaluated. Removal rates of methyl orange were determined by UV-Vis spectrophotometry and the adsorption process was found to be affected by initial dye concentration, adsorbant concentration, and pH. Adsorption isotherms were also plotted and showed a type III isotherm at pH 2, and a type V isotherm at pH 10. The adsorption of Eryngiumcreticum was then compared to other synthetic adsorbants and was found to offer similar adsorption capacity to some.

Keywords: Methyl orange, Eryngiumcreticum, adsorption, isotherm.
