Abstract

Background and purpose: Bisphenol A is an estrogenic substance that can cause endocrine dysfunction, which extensively enters water resources due to its large use in industry. The aim of this study was to synthesis modified magnetic nanoparticles with sodium alginate and study of its efficiency for removal of Bisphenol A from aqueous solutions using heterogeneous fenton process. Materials and methods: In present study, sodium alginate magnetic beads were synthesized by nanotechnology and chemical precipitation method and the removal of Bisphenol A was evaluated in a pilot-scale batch reactor. In addition, the effect of environmental factors, including pH, reaction time, catalyst dosage, initial concentration of Bisphenol A, and the concentration of H2O2 on removal efficiency of Bisphenol A was studied. The concentration of Bisphenol A in samples was measured by spectrophotometry instrument and the XRD method was applied to identify the characteristics of modified nanoparticles. Results: In this study synthesized modified magnetic nanoparticles with sodium alginate had complete magnetism properties, and XRD analysis confirmed the presence of Fe3O4. The results showed that the highest removal efficiency of Bisphenol A was obtained at pH=5, reaction time= 120 min, catalyst dose= 5 g/L, and initial concentration= 20 mg/L which was about 95. Conclusion: According to our results, the magnetic nanoparticles modified with sodium alginate in a heterogeneous Fenton oxidation process are highly efficient in removing Bisphenol A.
