用火焰原子吸收分光光度法测定钾长石中的氧化钾、氧化钠。
For the route of selective separation and enrichment with sodium oxide, it is very difficult for one-step route to produce quite pure enriched slag.对于钠系选择性分离富集路线,采用一步调渣法路线难以取得较高纯度的富钛渣。
The results showed that only small amount of alkalis in feldspar were extracted when autoclaved with water, and the majority of extract is sodium oxide.结果表明:长石在水中碱溶出量比较少,溶出的碱主要是钠碱。
