Synthesis of metal oxide nanoparticles using microorganisms and plants, so-called green synthesis methods, has received a great amount of attention because of its easy and inexpensive synthesis condition with respect to usual chemical and physical methods. The luminol chemiluminescent reaction is among well-known quantitative methods in analytical spectroscopy due to its high sensitivity to presence of catalyst and low background signal. In this study, Fe3O4/SiO2/ZnMn2O4 nanocomposite was prepared by the green method using Aloe Vera extract solution and characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and vibrating sample magnetometer (VSM). These magnetic nanoparticles were used as a catalyst in the luminol-H2O2 chemiluminescence system. The obtained results indicated that these nanoparticles have good catalytic activity in the chemiluminescence system so that the emission intensity was increased about fourfold in presence of catalyst at 3 second. The recovery of this catalyst was easily performed by an applying external magnetic field.
