原子吸收法测定橡胶中的铜

Determining Copper Within Rubber in Atomic Absorption Method

用空气—乙炔火争对橡胶中铜的原子吸收测量法进行试验研究：包括测量条件选择、干扰元素试验、消除干扰研究、分析方法拟订和分析测量的误差统计，该方法的灵敏度０．０５９×１０－６铜，标准方差０．００００３％铜，相对差小于１０％，为±５．７６％。

With atomic absorption method to measure copper within rubber by using air-acetylene flame, the wohole test and study for it contains selection of measuring condition,test of interference element, study on eliminating interference, tolerance statics of analytic method and measuring etc. The sensitivity of the method is 0.059×10 -6 ,standard square diference of copper is 0.00003%,less than 10% of relative tolerance is ±5.76%.
