Abstract
Abstract
Okra rod activated carbon was used as an adsorbent to remove levofloxacin in water. And effect of pH, adsorption time and adsorbent dosage on the adsorption effect were studied. The results were shown that the optimal pH was 5 and 10. The adsorption desorption equilibrium over Okra rod activated carbon was reached, when the adsorption time increased to 60min and 90min as pH = 5 and pH=10, respectively. Compared with the original Okra rod, the adsorption capacity of the Okra rod activated carbon was greatly improved. And the optimal dosage of Okra rod activated carbon was 50mg. The suitability of sorption isotherm model for the sorption of levofloxacin over Okra rod activated carbon is L Freundlich with high R2.
