| 摘 要： | 重晶石经Ｎａ２ＣＯ３熔融，水浸取，过滤。沉淀经ＨＣｌ溶解后，用电感耦合等离子体发射光谱法同时测定主成分ＢａＳＯ４和次量成分Ｆｅ２Ｏ３以及滤液中的ＳｉＯ２，结果与部颁标准方法符合。方法精密度好，主量组分ＢａＳＯ４测定的ＲＳＤ（ｎ＝６）为０．２４％，次量组分Ｆｅ２Ｏ３和ＳｉＯ２的ＲＳＤ（ｎ＝６）分别是３．６９％和１．４５％。

| Abstract: | Barite sample was fused with Na 2CO 3 and then converted into sample solution after water leaching, filtering, and precipitate was resolved by HCl. The major component of BaSO 4 and minor component of Fe 2O 3 in sample solution and SiO 2 in filter liquor were determined by ICP AES. The results were in agreement with that provided by the standard method. The precision for major component of BaSO 4 was 0.24% RSD ( n =6) and minor components of Fe 2O 3 and SiO 2 were 3.69% and 1.45% RSD ( n =6) respectively. |
