Introduction: The presence of antibiotics in drinking water negatively affects human health. The present study aimed atimproving the adsorption performance of tetracycline (TC) by adjusting biomaterial with MnMoO4, which is emanatedfrom aerobic algae.Methods: This is a fundamental and applied study in which Algae biochar composite and manganese molybdate as theeffective adsorbents in the removal of tetracycline antibiotics were used. This study has some objectives, which are asfollows: (a) characterizing composite (biochar modified by MnMoO4), (b) preparing an effective adsorbent for TCevacuation and giving a potential specialized help for TC wastewater treatment under different experimental conditionsthrough altering operational parameters, namely catalyst dosage, pollutant concentration, initial pH of the solution, and(c) concluding adsorption mechanisms, kinetic and equilibrium models that were employed in the experimental data.Results: The results indicated that The maximum adsorption performance of TC reached 81% in netural pH. It suggestedthat optimization of pH was taken into account in netural pH. The adsorption of TC on MMBC shows good agreement withthe pseudo-second-order model and the Langmuir isotherm.Conclusion: The results showed that algae biochar composite and manganese molybdate highly efficiently absorbedtetracycline. it can be used to remove contaminants from water.
