| 摘 要： | 硫酸钡重量法可用来测定硅铝钡中钡。实验人员可采用酸溶解试样，将不溶解的试样残渣回收，并选用EDTA络合干扰元素。在酸性条件下，钡与硫酸根形成硫酸钡沉淀。用此法得到的测定结果令人满意．

| Abstract: | The barium sulfate weight method can be used to identify barium in silicon aluminum barium sample. Laboratory technicians can dissolve test specimen with the acid, and recover the in dissolvable sample. Then they can selects the EDTA complexion disturbance element. Under the acidic condition, the barium and the sulfate radical form the barium sulfate precipitation. The method is applied in the barium determination in the silicon aluminum barium alloy, and the result is satisfying. |
