The goal of this work was to investigate the mechanism of competitive adsorption of naphthalene on activated carbons from diluted solutions. The polarity of the adsorption media was varied, by selecting solvents ranging from high to low dielectric constants (ethanol, cyclohexane and heptane). By altering the hydrophobicity of the adsorption media, the preferential adsorption of the organic probe is changed; the...
