Raw date palm waste was found to be an effective and environmentally friendly adsorbent for removing tetracycline and ciprofloxacin from water. The study examined the influence of various factors such as pH, biosorbent dose, antibiotic concentration, contact time, temperature, and salt concentrations. The pseudo-second-order model was the most suitable for describing the experimental data, and Langmuir and Dubinin-Radushkevich isotherms were found to be the best for TC and CIP adsorption, respectively. Thermodynamic parameters indicated that the process was spontaneous and endothermic.
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.
