目的：简化火焰原子吸收法测定食品中铅的萃取过程,减少复杂的操作过程中不确定因素对检测结果的影响,为取得准确的检测结果提供依据。方法对20份样品同时使用本法与国标法(GB5009.12-2010)测定,进行比对。结果对上述采用的两种方法的结果进行配对t检验,且t的界值表双尾概率范围是0.20<P<0.40。按照a=0.05的标准,则表明两种方法检测的结果相同,所以两者之间无统计学意义(t=0.89,P>0.05)。结论通过对其萃取方法的改进,其在测定食品中铅的含量中取得了良好效果,值得推广。

Objective Simplifying the process of extraction and flame atomic absorption spectrometry of lead in food, reduce the impact of the complex operation of uncertainty on the test results, and provide a basis for obtaining accurate results.Methods 20 samples simultaneously measured using a standard method and the National Law (GB5009.12-2010), for comparison.Results The two methods described above using the paired t test, and t the boundary value table is a two-tailed probability range 0.20 <P<0.40. A = 0.05 according to the standard, then the same results of the two methods, it was not statistically significant between the (t=0.89,P> 0.05). Conclusion By improving its extraction method, which achieved good results in the determination of lead in food, it is worth promoting.
