Abstract
Rhodamine B dye is a harmful contaminant in wastewater, so methods were developed to synthesize iron oxide nanoparticles that could catalyze the photodegradation of rhodamine B in water. Iron oxide nanoparticles were synthesized through the co-precipitation method and using FeCl2 as a source of Fe2+ ions. The nanoparticles were then characterized through IR spectroscopy and adsorption testing. Finally, a control solution of rhodamine B and an experimental rhodamine B solution with nanoparticles were exposed to UV light in a photo cabinet to analyze the degradation of rhodamine B over time using UV-Vis spectroscopy. IR spectroscopy showed that an iron oxide material had been synthesized, and adsorption testing revealed that rhodamine B adsorption equilibrium occurred around 95 min. The equilibrium dye adsorption Q value was 0.44 mg/g on the nanoparticles. The photocatalysis experiment showed little difference between the control and experimental solutions, with slopes of -1.5×10-3 mg/(L×min) and -1.7×10-3 mg/(L×min), respectively, and poor linearity with R2 values of 0.32 and 0.28, respectively. Overall, the results illustrate that an iron oxide nanoparticle material was synthesized and it was able to adsorb a moderate amount of rhodamine B. However, there was little degradation of rhodamine B in both the experimental and control solutions with almost no enhanced catalysis due to the presence of iron oxide nanoparticles.
