This study was undertaken to investigate the suitability of using a mixture of activated carbon (AC) and limestone (LS) as an adsorbate medium for removing high-strength colour from a semi-aerobic stabilized landfill leachate. Colour adsorption was explained by the Langmuir and Freundlich isotherms. Moreover, the adsorption kinetic mechanism was investigated using pseudo-first-order and second-order kinetics models. Approximately 88% of colour removal was achieved using a mixture of LS (35cm3) and AC (5cm3). In the current study, the Freundlich and Langmuir isotherms offered very good fits for colour adsorption with R2 values of more than 0.96. The empirical constant (n) value of the Freundlich isotherm was greater than 1, which implies a beneficial adsorption for colour. Results obtained from the kinetic models showed good compliance with the pseudo-second-order equation (R2 = 0.997). This indicates that LS can be used as a cost-effective medium to replace AC for colour removal at a considerably lower cost.
