PS4.0微机极谱法测定发样中微量铁
Determinate Iron in Hair By PS4.0 Micro-computer Polarography Instrument
【摘要】 本文采用PS4 .0微机极谱仪测定了发样中的微量铁 ,采用DTD4 0型恒温消解仪消化发样样品 ,检测下限 5 μg/L ,线性范围 10~ 2 5 0 μg/L ,发样测定的相对标准偏差为 3.70 %。回收率为97.4 %。锌、锰、铅 ,铜、镉不干扰测量 ,铁的PAR催化波与锰的催化波完全分离。分析结果满意
【Abstract】 The Paper uses PS4.0 micro-computer polarography instrument to determinate Fe 2+ in hair. TD40 model dry bath treat sample,the detection limit(nitrogen) is down to 5?μg/L. The relationship between peak current and the concentration of Fe 2+ is linear in the range of 5~250?μg/L,relative standard deviation is 3.7%. The recovery was 97.4%. Zn 2+ ,Mn 2+ ,Pb 2+ ,Cu 2+ ,Cd 2+ can not interfere to determinate. Fe 2+ Wave was separate with Mn 2+ Wave.The method has been used for determination of trace Fe with satisfactory results.
