In order to prevent abuse of low value-added rare earth, controlling rare earth content in ceramic color glaze is particularly important. This method provides a reliable basis for the development of entry-exit inspection and quarantine industry standards. Since the ceramic color glaze has extremely stable chemical properties, therefore can not use the traditional digestion method of sample preparation. Determination of Total 15 rare earth element in ceramic color glaze by inductively coupled plasma optical emission spectrometer was proposed in this paper, and sodium hydroxide and sodium peroxide were used to melt them. The research was focused on the digestion method, wavelength selection and matrix interference correction. A representative sample of ceramic color glaze was used to test recovery and accuracy and reproducibility. The values of recovery found were from 94.7% to 102.7% and precision of the method was below 2.7% and reproducibility was below 4.3%. The values of detection limits for 15 rare earth elements were below 0.51 mg·kg-1. ©, 2015, Chinese Rare Earth Society. All right reserved.
