| Résumé : |
An adsorption study was carried out with powdered activated carbon (PAC) prepared from leather buffing waste by steam activation after carbonization at temperatures between 500–800°C. Adsorption performance of each activated carbon test was carried out using methylene blue, a medium sized dye molecule commonly used to determine adsorption efficiency of adsorbents. The results obtained reveal an increase in adsorption of methylene blue with decrease in temperature of carbonization indicating that lower temperature of carbonization yields carbon with greater adsorption capacity. Also, this suggests that carbonization at temperatures below 500°C may be preferred. The carbon had adsorption capacity of 90.4mg/L of a solution containing 100mg/l of the dye. The effect of time and carbon dosage on adsorption indicates that activated carbon from leather buffing waste is competitive with the reference carbon indicating it can be used to adsorb dyes, decolorize organic compounds and treat waste water. Data corresponding to the adsorption of methylene blue onto the best activated carbon produced (BD5) using the Freundlich and Langmuir adsorption isotherm model established a fit with an R2value of 0.915 and 0.989 respectively. |
