据资料介绍,一般低含量铷的测定采用红外光区域,铊的测定采用紫外光或可见光区域,这样不能同时测定铷和铊,操作也较麻烦。本法采用硫酸钾为缓冲剂,利用大量碱金属抑制氰带的产生,上电极填满硫酸钾与二氧化硅的混合物,加大极距,截取弧焰的 According to the information, the determination of low content of rubidium using infrared light region, the determination of thallium using ultraviolet light or visible light region, so can not simultaneously determine rubidium and thallium, the operation is more troublesome. This method uses potassium sulfate as a buffer, the use of a large number of alkali metal inhibition of the production of cyanide, the upper electrode filled with a mixture of potassium sulfate and silica, increase the polar distance, interception arc flame
