SINTESIS CdFe2O4 UNTUK FOTODEGRADASI DAN ADSORPSI ZAT WARNA METILEN BIRU
Research of CdFe2O4 synthesis through coprecipitation method and its application for photodegradation and adsorption of methylene blue dye had been conducted. CdFe2O4 nanoparticles were characterized by using XRD, SEM-EDS, VSM and UV-VIS DRS. Diffraction pattern of XRD characterization shows the highest peak at 2θ = 30.29° with a crystal size of 18.70 nm. Furthermore, SEM-EDS characterization image shows that the surface morphology of CdFe2O4 is heterogeneous or agglomerated with the main constituent elements in the form of Cd (24.66%), Fe (26.61%) and O (32.76%). The VSM characterization result from the hysteresis curve obtained saturation magnetization of 28.14 emu/g. In addition, the result of UV-VIS DRS characterization obtained an energy band gap of 1.74 eV. CdFe2O4 nanoparticles has pHpzc of 5.35. Meanwhile, the optimum conditions for photodegradation and adsorption are obtained at a concentration of 2.5 ppm, contact time for 90 minutes with the addition of 0.2 mL of H2O2 30% with the percentage of methylene blue dye removal by photodegradation is 77.21% and adsorption is 67.99%. TOC analysis shows the total amount of carbon before degradation is 0.7716 ppm C and after degradation is 0.5643 ppm C with a percentage of degradation is 26.87% which indicates that the methylene blue dye is not completely oxidized.
