| Popis: | The Gelatin/Activated Carbon Composite (GE/AC) adsorbent in bead form was prepared and used to adsorb Rhodamine B from an aqueous solution. Gelatin and activated carbon were combined to an eco-friendly, non-toxic, non-carcinogenic, biocompatible and inexpensive biosorbent. Dependence of sorption performance on key factors, such as contact time, adsorbent dosage, pH, and temperature, were experimentally examined. The effects of initial Rhodamine B concentration were also evaluated, and the response followed Langmuir adsorption isotherm, with the maximum adsorption capacity of 256.41 mg g −1 at pH 4 and 30 °C. The results indicate that the GE/AC adsorbent has potential to serve in wastewater treatment applications, especially in batch removal of Rhodamine B from an aqueous solution. |
