Adsorption of Cefradine onto Powder and Activated Carbon Prepared from Orange Peel

Abstract:

The adsorption of cefradine was carried out using biological adsorbents of powder and carbon prepared from orange peels, an agriculture by-product. The equilibrium was easily reached in less than 10 minutes, with adsorption rates of more than 98%. Cefradine showed a firm combination to the adsorbent, which could hardly be damaged or affected by pH values. After equilibrium was reached within 1 h, no desorption behavior was observed in the next 30 minutes. The adsorption process could be well fitted thermodynamically to both Freundlich and Langmuir equations. Similar results could also be obtained using ashes of orange peel, as well as carbon prepared from pistachio and peanut hull, indicating an attractive option to treat industrial wastewater.
