چکیده

Abstract:

In the current study, a novel Al-Ti2O6 nanoparticles and polysulfone composite membranes were prepared and used for the removal of heavy metal ions. Al-Ti2O6 was prepared by precipitation method and the membranes were prepared by diffusion induced phase separation method with different compositions of Al-Ti2O6. The prepared Al-Ti2O6 nanoparticle was confirmed by XRD, and SEM analysis. However, FE-SEM was used to confirm the presence of nanoparticles in the membrane. EDX and elemental mapping were performed to confirm uniform distribution of nanoparticles in the membranes. The hydrophilicity of the membrane was measured by contact angle, water uptake and water flux study and it was increased with respect to increasing concentration of nanoparticles. Performance of the membrane was analyzed by rejection of heavy metals such as As, Cd, and Pb. The membrane was showed rejection percentage of about 96 % for As, 98% for Cd and 99% for Pb. The concentration of nanoparticles and filtration time was investigated in detail. The obtained results prove Al-Ti2O6 a mixed metal oxide composite membrane a potential candidate for the removal of As, Cd, and Pb.

Conclusion

The proposed membrane showed effective impact on removal of heavy metal ions like As, Cd and Pb. This work involves a foremost, budgetary, simplistic technical method and most effective method to procure heavy metal ions present in aqueous solution. The well dispersed hydrophilic NPs additives were prepared by using simple co-precipitation technique. The presence and uniform distribution of the additive into the membrane matrix was confirmed by elemental mapping. The results revealed that, modified membranes displayed enhanced porosity, water uptake capacity, hydrophilicity as well as the heavy metal ion adsorption and all together played an important role in the high rejection of the heavy metal ions. Also the modified membrane exhibited superior pure water fluxes. Overall the NPs are an effective inorganic additive to improve the membrane performance and it can be employed as a potential candidate for the further studies.
