1引言标准溶液是广泛用于校正测量装置、评价分析方法、考核分析人员及测量的长期质量保证,可使被测的或已确定的量值在不同的地区传递,在保证化学测量的准确一致、分析测试结果的质量方面具有重要作用。目前,核工业系统对核燃料和核材料的分析大多采用ICP光谱法或化学光谱法, 1 Introduction Standard solution is widely used in the calibration of measuring devices, evaluation methods, assessment of analysts and measurement of long-term quality assurance, the measured or determined value can be passed in different regions, to ensure accurate and consistent chemical measurement , Analysis of the quality of test results has an important role. At present, most of the nuclear industry systems analyze nuclear fuel and nuclear materials using ICP spectroscopy or chemical spectroscopy,
