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.
