【摘要】 采用电感耦合等离子体质谱法快速测定了尿、血液和头发中的铊含量。以115In作内标,方法检出限为0.005 5 ng.mL1(3δ),标准曲线范围为1~1 000 ng.mL1(r=0.999 8),相对标准偏差为2.8%(n=10),加标回收率在94%~104%之间。更多还原

【Abstract】 The method for rapid determination of thallium in urine,blood and hair by the inductively coupled plasma mass spectrometry has been developed.115In was internal standard.The limit of detection of the thallium is 0.005 5 ng·mL-1(3σ).The standard curve range of thallium is 1~1 000 ng·mL-1(r=0.999 8).The relatively standard deviation of thallium is 2.8%(n=10).The recovery of thallium is 94%~104%.更多还原
