| 摘 要： | 建立了氢化物发生-原子荧光光谱法同时测定铁鳞中砷和汞的新方法。样品采用盐酸（1+1）分解，加入硫脲-抗坏血酸混合溶液作为还原剂和掩蔽试剂，以氢化物发生-原子荧光光谱法进行检测。详细研究了样品酸度、硫脲-抗坏血酸浓度、还原时间、硼氢化钾浓度、载流、基体效应等因素对测定结果的影响，并确定了最佳检测条件。本方法砷和汞的检出限分别为0.036 μg/g和0.010 μg/g；相对标准偏差（RSD）分别为5.1%和8.8%（n=11，As为1 μg/g，Hg为0.2 μg/g），回收率介于95%~110%之间。

| Abstract: | A new method has been developed for the determination of arsenic and mercury in mill scale by hydride generation atomic fluorescence spectrometry.The samples were digested by HCl(1+1),and arsenic and mercury in sample were determined by hydride generation atomic fluorescence spectrometry with addition of thiourea-ascorbic acid mixed solution as reductant and masking reagent.The influencing factors were investigated,including the sample acidity,thiourea-ascorbic acid concentration,reduction time,potassium bo... |
