摘　　要：为了有关行业对碘分析、监测及评价结果的准确一致而设计和制备海带中碘成分分析标准物质 ,可用于有关行业的技术培训、考核、仲裁、验证等工作。本标准物质用中子活化法等 6种不同原理、分析方法进行定值。按格拉布斯法则判定每组数据 ,正态性D检验确认 6组定值的实验数据为正态分布。低碘量和中碘量海带标准物质总算术平均值分别为 9 3、85 7μg g ,标准偏差分别为 0 9、4 9μg g。Analytical reference material of iodine in kelp was designed and prepared for accurate analysis, monitor and evaluation of iodine in trade of farming, forestry, medicine and food hygien can be used in technical training, technical assessing, monitoring, date arbitrating and analytic method verifying for professional supervisors. This reference material was certified by neutron activation, ICP-MS, PA, GC, IC, COL method. According to Gurbb's law to judge the date of each group, it was confirmed that all of six groups certified curde date were normal distribution by checking normality D. The arithmatic mean value of all data on certified reference material of low and moderate amount was 9.3μg/g and 85.7μg/g respectively and , standard deviation was 0.9μg/g and 4.9μg/g respectively.
