离子色谱法（安培检测器）测定血清尿及头发中微量碘

his paper intreduces a reasonable pretreatment method for IC-amperometric method employed to measuretrace amount of iodine in serum, urine and hair. The resultant graph is simple and clear,and withoutinterference in a general way. The limits of detection for iodine in serum,urine and hair are 0.007,0.003g/mL and 0. 046g/g, respectively.The recovery of iodine added into the sample is 82～93%. The coefficient ofvariation is less than 9%. Trace amount of bromine in the sample can also be measured simultan 戴安仪器:DX120 赛默飞戴安ICS-2100离子色谱系统
