Synthesis of rod-like CeO nanoparticles and their application to catalyze the luminal-O chemiluminescence reaction used in the determination of oxcarbazepine and ascorbic acid.

Rod-like CeO nanoparticles (NPs) were produced by the quick precipitation approach and employed as a catalyzer to increase the chemiluminescence (CL) intensity of the luminol-O reaction. The transmission electron microscopy (TEM) images of the CeO NPs showed that rod-like particles with the length and diameter about 15 nm and 5 nm, respectively, were produced. Furthermore, pharmaceuticals including oxcarbazepine (OXP) and ascorbic acid (AA) showed an inhibitory effect against the CL intensity such that the more concentration of the pharmaceuticals, the less was the CL intensity.
