- The Determination of REE Tracers by INAA
- Keywords:
- INAA; tracing REE; acctiracy; soil erosion
- 摘要:
- 介绍了中子活化分析法的基本原理，分析REE的方法步骤、含量计算及误美来源。结果表明：利用仪器中子活化分析（INAA）可精确测定沉积泥沙中REE的含量，对涉及的REE三次重复精密度偏差小于10%，其准确度完全能够满足REE示踪法研究土壤侵蚀的精度要求。
- Abstract:
- The determining rnethod of REE tracers by using INAA, including the principles,operating steps, content calculation, and error sources, has been introduced in this paper.Experimental results show that INAA can determine precisely the contents of REE tracers in sediment. Theprecision of three replication for ench of the samples were less than ±10% for the tracing elements. The accuracy were evaluated by comparison of our values for the SRM standards,which was considered satisfactory the requirement of soil erosion researches.
