Effects of Titanium Dioxide (TiOz) on the Characteristics of Fabricated Polymer Inclusion Membrane for Removal of Reactive Orange (RO16) dye ABSTRACT

Polymer inclusion membrane (PIMs) one of the liguid membrane technology that effective and efficiently to remove reactive orange 16 (RO16) dye from aqueous solution.
This removal method is used since it is more conveniently and economical than other dye removal technologies. The polymer inclusion membrane which including PVDF-Co-HFP as the base polymer, Methyltrioctylammonium chloride (Aliquat 336) as the carrier and titanium dioxide (TiOz) nanoparticles as additive were used during the membrane fabrication. Furthermore, the fabricated membrane with titanium dioxide (TiOz) nanoparticles also characterized viaScanning Electron Microscopy (SEM), Thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), Electrochemical Impedance Spectroscopy (EIS), Ion Exchange Capacity (IC), and water uptake in terms of surface morphology, thermal stability, functional group, membrane resistance, ion exchange capacity and wettability during PIMs fabrication. In this research, the surface morphologies for M2 showed the patches pores formed. Next, the thermal stability for fabricated membrane increases when the TiO2 content increases. The functional group in M2 membrane also showed the presence of hydrogen bond between R016 dye because a peak at 3390.56 cm was disappeared. Furthermore, M2 showed low membrane resistance compared to M5 due to addition of TiO2. The ion exchange capacity and water uptake of M2 also showed that when the addition of Ti02 increases, the ion exchange capacity and wettability of membrane increases respectively. Besides, various parameters such as pH and amount of TiO, nanoparticles also were observed. The RO16 dye removal by PIMs were found to be efficiently at M2 composition (0.2g of TiOz nanoparticles; pH 2; 10 mg/L; 4 hours; 500 rpm) with 99.75% of removal efficiency.
Thus, it is proven that PIMs with additional of TiOz nanoparticles have the ability to remove reactive orange 16 (RO16) dye from aqueous solution.
