| 摘 要： | 在硫酸铵的作用下,控制溶解温度,钛白粉能够缓慢溶解在浓硫酸中,而在一定的酸度条件下,三价铁与硫氰酸铵能够快速形成稳定的红色络合物,由此确立了测定钛白粉中微量铁的方法。该测定方法具有快速、简便、重现性好、准确度高的优点,适用于钛白粉成品中铁含量的分析。

| Abstract: | Under the role of ammonium sulfate,titanium dioxide can be slowly dissolved in sulfuric acid by controlling the solution temperature.Under the condition of a certain acidity,the ferric iron can quickly form a stable red complex with ammonium thiocyanate.Thus the determination method of trace iron in titanium dioxide was established.The method possessed the advantages of fastness,simplicity,good reproducibility and high accuracy,and is suitable for the analysis of iron content in titanium dioxide. |
