Abstract Due to increased pharmaceutical sewage, the cost efficient adsorbent is extremely needed for medical wastewater treatment. Bentonite which is consists essentially of clay minerals of the smectite group; have a wide range of industrial uses. In this study, a simple approach to adsorb Tetracycline (TC) from aqueous solution by exchangeable cation by bentonite clay is presented. The effects of contact time, initial TC concentration, adsorbent dosage, and solution temperature on the adsorption of TC ions from solution were investigated. The theoretical capacity of bentonite clay adsorbent is about 31.4 mg/g. The optimum adsorption conditions were recommended.
