| Abstract: | Under the condition of the optimization of the instrument, the content of iodine in urine was established by ICP-MS method, using In as the internal standard. The sample was determined directly after diluted and eentriμlge. The recovery is between 95.3% and 98.1%. And the relative standard deviations are from 1. 15% to 2.08%. Its linear correlation coefficient is 0. 99997. The conten.t of iodine in 25 samples was determined simultaneously with ICP-MS method and national standard method. All data were analyzed by paired-sample T test. T= 0. 158 less than 2. 021, P〉 0.05. The results had no significant difference. The ICP-MS method is simple, quick, widen Linear range, highly sensitive and less disturbance. It is suitable to determine a large scale of the content of iodine in urine. |
