摘要
采用发射光谱载体分馏法测定WO3中Zn、Zr、Sr、Ba、Ag的含量．试验中，选择了含3．5％氟化锂、4．0％碳酸锂的石墨粉作缓冲剂，选择了适宜的分析线和光谱测定条件．测定下限分别为：Zn、Zr0.001％，Ba0.0007％，Sr0．0005％，Ag0．0002％．
The carrier distillation methed of optical emission spectrographic analysis is used to determine for Zn.Zr.Sr.Ba.Ag inWO3 The mixture of 3. 5 % LiF and 4. 0% Li2CO3 and 92. 5 % graphite powder is used as buffer. The suitable spectrochemical analytic lines and condition are selected. The lower concentrations of deterndnation are separatly Zn. Zr 0. 001 %, Ba0.0007%,Sr 0.0005 %,Ag 0. 0002 %.
