摘要
本文研究了单缝石英管贫焰捕集 脉冲富焰释放原子捕集原子吸收光谱法测定净水剂中的铅 ,对测定条件和干扰元素进行了探讨 ,拟定了简便、快速测定净水剂中铅的新方法。本法线性范围为 0～ 10 0 μg·L-1,回收率为 97%～ 10 3% ,相对标准偏差为 2 6 %～ 2 8% ,用于实际样品中铅的测定 。
The determination of lead in water depuration agent with single-slotted quartz tube by the fuel-lean flame trapping and pulsed fuel-rich flame discharge atom-trapping atomic absorption spectrometry have been investigated. The optimum conditions for the determination and the tolerance of interfering elements are studied. A simple and rapid method is proposed. The linear relationship holds in the range 0-100 mug.L-1, the recovery is between 97 % -103 % and the relative standard deviation is 2.6 % -2.8 %. The proposed method has been applied to the determination of lead in water depuration agent samples with satisfactory results.
