Abstract

The ko-standardization method is suitable for routine multielement determinations by reactor neutron activation analysis (NAA). Investigation of NIST standard reference materials SRM 1571 Orchard Leaves, SRM 1572 Citrus Leaves, and SRM 1573 Tomato Leaves showed the systematic error of 12 certified elements determined to be less than 8%. Thirty-four elements were determined in NIST proposed SRM 1515 Apple Leaves.

摘要

ko标准化方法适用于通过反应堆中子活化分析（NAA）进行的常规多元素测定。对美国国家标准与技术研究院（NIST）标准参考物质SRM 1571果园树叶、SRM 1572柑橘树叶和SRM 1573番茄树叶的研究表明，所测定的12种认证元素的系统误差小于8%。在美国国家标准与技术研究院提议的SRM 1515苹果树叶中测定了34种元素。
