摘    要:采用碱熔法分解铬铁矿,并用硫酸亚铁铵滴定法测定三氧化二铬质量分数,对比了不同熔剂对测定结果的影响.结果表明,以质量比为2∶1的过氧化钠和氢氧化钠作为熔剂熔融分解铬铁矿,样品分解完全,测定结果准确可靠.

关 键 词:铬铁矿  碱熔  分解  三氧化二铬

Abstract:By alkali melt method of decomposition of chromite,the ammonium ferrous sulfate titration was used to determine the content of chromium trioxide.The effect of different flux on the determination results influence was compared.The results show that with sodium peroxide and sodium hydroxide(weight ratio 2∶1)as the flux melt decomposing the chromite,the samples were decomposed completely,and the determination result is accurate and reliable.
Keywords:chromite  alkali fusion  decomposition  chromium sesquioxide.
