本文对八种载体物质在测定高纯锌杂质中的效果作了比较,并选择了其他合适的测定条件。本法的要点是:先将金属样品转化为氧化物,然后加入5%氟化钡,磨匀,装入直径3.5亳米,深3.5毫米的孔状电极,用250V、10A直流电弧进行激发,在φC—13—1型光栅摄谱仪上摄谱,能同时测定18个杂质元素,其测定下限为0.03～1ppm,相对标准偏差为±5～20%。文中并对氟化钡的作用机理提出了初步的看法。
In this paper, eight kinds of carrier substances in the determination of high-purity zinc impurities were compared, and choose other suitable measurement conditions. The main points of this law are as follows: Firstly, a metal sample is transformed into an oxide, then 5% barium fluoride is added, and the mixture is evenly ground into a hole electrode with a diameter of 3.5 millimeters and a depth of 3.5 millimeters for excitation with a 250V, In the φC-13-1 grating spectrograph photographed, can simultaneously measure 18 impurity elements, the lower limit of determination of 0.03 ~ 1ppm, the relative standard deviation of ± 5 ~ 20%. The paper also put forward a preliminary view on the mechanism of action of barium fluoride.
