This paper uses ICP-AES methods to detect europium oxide in rare earth carbonate and rare earth chloride,the effect of coexisting impurity elements in different matrix and different matrix distribution on determining element was investigated systematically.Recovery ratio and precision experiments were carried out,the result is accurate in comparison with the ICP-MS method. Determining range is 0.01%～0.30%.
