Abstract
- 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, magnetic nanocomposite of Fe3O4/SiO2/TiO2/CoIIITHPP (THPP : tetrahyroxyphenylporphyrin) has been synthesized by co-precipitation method and characterized with fourior transform-infrared (FT-IR), X-ray photoelectron spectroscopy (XRD), vibrating sample magnetometer (VSM), scanning electron microscope (SEM), trasmiddion electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS. For the fist time, this magnetic nanocomposite has been used as catalyst of chemolumincence reactions and showed high catalytic effect on the luminol-H2O2 system. The recovery of catalyst was easily performed by applying the external magnetic field.
