abstract = " In this study, the color adsorption capacity of CFA from PME was determined. A total number of nine (9) batch studies from the combinations of the three (3) CFAs samples from Georgia Power Company and the three (3) PMEs samples were performed. In each batch study, a complete set of dosage screening, kinetic and isotherm studies was conducted and the data was fitted to existing adsorption models. Based on the results, the effective CFAs dosages for the majority of nine (9) combinations were in a wide range of 30 - 100 g/L for 80% color removal from PMEs while the adsorption equilibriums were achieved in a wide range of 2-24 h for different CFAs. For the kinetic study, the correlation coefficient R 2 value for each combination indicates that the pseudo-second-order kinetic model was better fitted for both bituminous and sub-bituminous Class “F” CFAs than the pseudo-first-order kinetic model. Based on the results from the isotherm studies and the application of the isotherm models, the color adsorption capacities of CFAs varied in a wide range of 1.2-23.8 mg/g. Overall, this study found CFAs to be a promising low-cost adsorbent for the removal of color from PMEs.",
