Abstract：In order to investigate the content and distribution of rare earth elements (REE) in main economic macroalgaes in our country, fifteen rare earth elements in three economic macroalgaes (including 30 samples of kelp, 30 samples of laver and 15 samples of Enteromorpha) were detected using ICP-MS method. Results showed that the total content of REE in different species of macroalgaes was different. The highest total content of REE was in Enteromorpha (16 012.0 ng·g-1), while in kelp and laver, the total REE was similar for two macroalgaes (3 887.4 and 4 318.1 ng·g-1 respectively). The content of fifteen rare earth elements in kelp ranged from 7.9 to 1 496.4 ng·g-1; in laver, it ranged from 8.2 to 1 836.6 ng·g-1. For Enteromorpha, the concentration of 15 rare earth elements were between 19.2 and 6 014.5 ng·g-1. In addition, the content and distribution of different rare earth elements in different macroalgaes was also different. For kelp, the highest content of REE was Ce (1 496.4 ng·g-1), and the second was La (689.1 ng·g-1). For laver, the highest was Y (1 836.6 ng·g-1), and the second was Ce (682.2 ng·g-1). For Enteromorpha, the highest was Ce (6 014.5 ng·g-1), and the second was La (2 902.9 ng·g-1). Present results also showed that three macroalgaes accumulated the light rare earth elements much more than the high rare earth elements. The light rare earth elements occupied 90.9%, 87.3% and 91.1% for kelp, laver and Enteromorpha respectively. The result that the Enteromorpha had high content of rare earth elements could provide important support for opening new research directions for the utilization of Enteromorpha.
