摘要
采用氢氧化钠、过氧化钠熔解钛铁矿样。对样品中钛、铁含量采用同一份待测液分别取样后,用二安替比林甲烷比色法和磺基水杨酸比色法进行测定。分析结果表明,该方法具有较好的准确度,能满足分析要求。是一种快速、低耗,能大批量分析测试的方法。
The ilmenite sample is dissolved with sodium hydroxide, sodium peroxide. For Ti, Fe content, from the same one solution for examination is sampled separately, thsn examined with colorimetric analysis. The a- nalysis method is accurate, rapid, low expense and can be carried out for a great batch of samples.
