摘要
通过对高岭土中铁含量测定方法的比较，选择以邻菲口罗啉法作为煤系高岭土中铁含量的测定方法．该法测定结果准确，尤其对含铁量较低的高岭土更为适合．在试验的基础上确定了测定方法的主要条件为：显色剂５ｍｌ２％邻菲口罗啉溶液，还原剂４ｍｌ１０％盐酸羟胺液．
Comparisons have been drawn between several measuring methods and the O phenanthroline method is selected for the determination of iron content in coal seam kaolin.Primary measuring conditions for the method have also been determined.
