摘要
目的改进国标面制食品中铝的测定方法。方法在其反应体系中加入OP—10乳化剂。结果方法的线性范围0 5μg/m l,相关系数r=0.999 6,RSD为2.12%2.97%,加标回收率为90.5%103.8%。结论该方法显色灵敏,稳定性好,准确,干扰少,适用于面制食品中铝的测定。
Objective To improve the Chinese national standard method which determines alumium in cooked wheaten food. Method OP-10 emulsifier was added in the reaction system. Result The linear range of the method was 0 -5μg/ml（r =0. 999 6）. The RSD was 2. 12% -2. 97%. The average recovery rates were 90. 5% - 103.8%. Conclusion This method is sensitive, steady, accurate and has low interference. It is suitable for the determination of aluminum in cooked wheaten food.
