摘要
本文研究了微量元素硒 ,用APDC和MIBK萃取 ,火焰原子吸收法进行测定。通过萃取富集 ,既克服了硒的原子化效率低而难以测定的缺点 ,又消除了稳定剂Cu2 + 及样品中所含有的其他金属离子对硒测定的干扰。用于高粱种皮中硒的测定 ,效果良好。方法简单、快速、准确 ,具有较高的准确度和精密度。相对标准偏差为 4 18% ,回收率为 97 8%。
This paper reports the determination of selenium by FAAS, extracted with APDC and MIBK ,Being extracted and enriched, it not only overcomes the shortcomings, being difficult to determine selenium for the low efficiency of atomization, but also climinates the disturbance in determination of selenium from the stabilizer Cu2+ and the other metal ions in the sample. The method was applied to the determination of selenium in the husk of kaotiang and had a good effect. The method is simple and rapid with good precision and accuracy. The relative standard deviation is 4.18 %. The recovery is 97.8%
