Equation predicts adsorption of oxygenated petchems on activated carbon

This article presents the results of a correlation that accurately estimates the adsorption capacity of activated carbon for removing oxygenated petrochemicals in water. Adsorption on activated carbon is an effective method for water purification.Results use the Freundlich equation for adsorption capacity as a function of the compound concentration in aqueous liquid. The correlation constants are presented in a tabular format, which makes for rapid engineering use. Correlation and experimental results agree favorably.Previous articles (OGJ, May 5, 2003, p. 80; Apr. 12, 2004, p. 66) developed correlations for the adsorption capacity of activated carbon for alkyl benzenes in water and chlor...
