title: [Study on certified reference material of iodine in kelp].
abstract: 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 hygiene 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 arithmetic mean value of all data on certified reference material of low and moderate amount was 9.3 microg/g and 85.7 microg/g respectively and, standard deviation was 0.9 microg/g and 4.9 microg/g respectively.
