Adsorption of Tetracycline and Ciprofloxacin from Aqueous Solution on Raw Date Palm Waste

Raw date palm waste was investigated as an adsorbent to remove tetracycline (TC) and ciprofloxacin (CIP) from water. Influence of pH, biosorbent dose, starting antibiotic concentration, contact time, temperature, and concentrations of different salts were examined. The pseudo‐second‐order model prov...

Description
Summary:Raw date palm waste was investigated as an adsorbent to remove tetracycline (TC) and ciprofloxacin (CIP) from water. Influence of pH, biosorbent dose, starting antibiotic concentration, contact time, temperature, and concentrations of different salts were examined. The pseudo‐second‐order model provided the best fit to the experimental data, while Langmuir and Dubinin‐Radushkevich isotherms were found to be the most suitable for TC and CIP adsorption at equilibrium, respectively. Thermodynamic parameters indicated that the process is spontaneous and endothermic. These findings suggest that this waste could be a cost‐effective and eco‐friendly adsorbent to remove antibiotics from wastewater. Date palm fiber was tested as sorbent for tetracycline and ciprofloxacin removal. The effects of pH, sorbent dose, and initial antibiotic concentration on adsorption were studied. Langmuir and D‐R isotherms provided the best fit to the experimental data of tetracycline and ciprofloxacin biosorption, respectively. Date palm waste appears to be a viable sorbent to remove antibiotics from wastewater.
