Abstract

This research aims to analyze surface characteristic of zinc ferrite nanoparticles based on the N2 adsorption isotherm. The morphology and size of zinc ferrite nanoparticles were observed using a scanning electron microscope. Analysis of N2 adsorption isotherm using the Brunauer- Emmett-Teller  equation  obtained  a  specific  surface  area  of  9.78  m2/g  and  mesoporous structure.    Zinc  ferrite  nanoparticles  were  composed  of  spherical  primary  particles  with  a diameter  of  67  nm.  The  size  of  the  nanoparticles  obtained  from  the  specific  surface  area analysis was greater than the scanning electron microscope image analysis. This finding shows that zinc ferrite nanoparticles are agglomerating to form larger secondary particles.Keywords: Zinc ferrite, nanoparticle, surface area, agglomeration

Abstract

Advanced  Oxidation  Processes  (AOPs)  is  one  of  the  methods  used  to  treat  organic  dye  waste. Powder-based  AOPs  as  photocatalyst  have  disadvantages  due  to  surface  adsorption  and agglomeration, thereby reducing the percentage of dye decomposition. In this study, the addition of  chemical  energy  (photo-Fenton-like)  and  ultrasonic  waves  (sono-photocatalyst)  in  the photocatalyst process was used to increase the activity of powder-based photocatalyst material as a  decomposer  of  Rhodamine  B  organic  dye.  The  photocatalyst  material  used  was  ZnFe2O4 nanoparticles synthesized using precipitation method with a calcination temperature of 700oC for 3 hours. The combination of light energy (4.69 eV) and chemical energy (44 meV) in the photo- Fenton-like process showed the highest percentage of Rhodamine B decomposition (70%). The use of  ultrasonic  energy  (28  meV)  in  the  sono-photocatalyst  process  increases  the  rate  of decomposition  of  RhB  by  2  times.  The  addition  of  chemical  energy  (44  meV)  increased  the photocatalyst activity of ZnFe2O4 nanoparticles on decomposition of RhB by 8 times. The results showed that the addition of chemical energy to the photocatalyst  activity of ZnFe2O4 was much more efficient than the addition of ultrasonic energy.
