石墨炉原子吸收法测定家禽饲料中的钼

用石墨炉原子吸收法测定家禽饲料中的钼，采用预烘干一湿法酸消解处理样品，抗坏血酸做基体改进剂。在探索不同原子化温度与灰化温度的多种优化实验条件基础上，对家禽饲料中的钼进行了测定。实际样品加标回收率为92．0％-106．0％，相对标准偏差为1．78％。该方法与其他方法比较具有快速、准确、灵敏、干扰小、操作简单、重现性好等特点，结果令人满意，值得推广。

Molybdenum Detecting in Poultry Forage by Graphite Furnace Atom Absorption Spectrometry

Graphite furnace atomic absorption spectrometry is used to detect molybdenum in poultry forage with pre-drying and wet-acidolysis method,and ascorbic acid was used as matrix modifier.Molybdenum detecting in poultry forage is done based on studying the priory experimental conditions by comparing many kinds of different atomization temperature and ashing temperature.The recovery of detected elements from samples varied from 92.0% to 106.0% and RSD was 1.78%.The method was rapid,accurate,sensitive and simple.The obtained results agreed well.
