ICP-AES快速测定钛铁矿精粉中钛、铁、钒的含量

摘要

Titanium dioxide content of Ilmenite concentration is generally 40%~50%,and total iron content is generally 30%~45%.Both will cause interference to the determination of other components during the analysis process of ilmenite concentration.A lot of hydrolysis of titanium can cause failure in analysis work.Samples are de-composed by using hydrofluoric acid-aqua regia-sulfuric.In 8%sulfuric acid and 10%hydrochloric acid medi-um,using ICP-AES national standard material as the standard curve,the contents of titanium,iron,vanadium in ilmenite fine flour can be rapidly determined.The method is simple,selective and accurate.%钛铁矿精粉中二氧化钛的含量一般在40％～50％，全铁含量一般在30％～45％，二者在钛铁矿精粉分析过程中对其他组分测定造成干扰，同时大量钛的水解会造成分析工作的失败，通过氢氟酸-王水-硫酸分解样品，在8％的硫酸和10％的盐酸介质中，用ICP-AES以国家标准物质作标准曲线，快速测定钛铁矿精粉中钛、铁、钒的含量，该法简便快速，选择性好，准确度高。
