本文研究了不分离大量共存铝而测定煤中的铍。形成的Be—SCR—CTMAB胶束增溶三元络合物稳定。在0～3.2μgBe/50ml时符合郎比定律,ε_(575)=4.8×10~4。操作简便,可用于煤,石煤中铍的测定。
This paper studies the determination of beryllium in coal without separating large amounts of coexisting aluminum. The formed Be-SCR-CTMAB micellar solubilized ternary complex is stable. In the 0 ~ 3.2μgBe / 50ml when in line with the Langbai’s law, ε_ (575) = 4.8 × 10 ~ 4. Easy to operate, can be used for determination of beryllium in coal and stone coal.
