Photodegradation for Tetracycline Chloride from Water by using Electric Arc Furnace Dust

Sabah S. Ibrahim

ABSTRACT: Increasing concentrations of antibiotics including tetracycline chloride in surface and groundwater are a major environmental concern in recent years. In this research, the potential of electric arc furnace dust for efficient removal of tetracycline chloride residue from aqueous solutions was investigated. For this purpose, electric arc furnace dust was characterized by XRD, surface area and TEM techniques. Effect of various parameters such as contact time, adsorbent dosage, initial concentration of tetracycline chloride and temperature on adsorption of tetracycline chloride on electric arc furnace dust was investigated. The results showed that the best condition for removal of tetracycline chloride was exhibited at contact time 120 min and adsorbent dosage 1g/L. the removal of tetracycline chloride decreased with the increase of initial concentration. Langmuir and Freundlich isotherm models were applied to the equilibrium data. Results indicate the potential of electric arc furnace dust for removal of tetracycline chloride from aqueous solutions.
