不经分离直接测定强化牛奶中的氟含量，方法的回收率为９３．７５％（加入氟８μｇ）～１０１．２％（加入氟１６μｇ），相对标准差为３．７６％。并检验了样品空白标准曲线与试剂空白标准曲线的相关性，二者之间无显著性差异（Ｐ＞０．０５）。方法简便快速、准确可靠，适合于生产部门的常规测定。
The recovery of the method was 93.75% (fluorine 8μg) ~ 101.2% (fluorine 16μg) with the relative standard deviation of 3.76%. The correlation between the blank curve of the sample and the blank curve of the reagent was tested. There was no significant difference between the two (P> 0.05). The method is simple and fast, accurate and reliable, suitable for the routine determination of the production department.
