摘要

    摘要
  • 摘要: 高岭土中铁的赋存状态和含量影响其白度和增白效果,因此快速准确地测定高岭土中不同种类的铁含量具有实际应用意义。高岭土中自由铁和结构铁定量分析困难,为此本文将高岭土中的铁分为可溶铁和非可溶铁两类。高岭土经盐酸酸溶处理后溶液中的铁含量为可溶铁含量,经氢氧化钠碱熔处理后溶液中的铁含量为总铁含量,非可溶铁含量由总铁含量减去可溶铁含量计算得出。采用邻菲啰啉光度法测定溶液中的铁含量,该方法的相对标准偏差小于5%,加样回收率范围在95%~105%,最低检测含量为1.06 μg/g。高岭土中的其他元素对铁的测定均没有干扰。所测得的可溶铁为大部分自由铁和少数结构铁。通过对高岭土中的可溶铁进行定量分析,可得知漂白工艺中可除去的最大铁含量。
    Abstract: The whiteness and whitening effect of kaolin are influenced by the status and content of iron in kaolin. It is meaningful in practical application to determine the contents of different species of iron in kaolin rapidly and accurately. However, it is difficult to analyze the contents of free and structural iron in kaolin. In this article, iron in kaolin is divided into soluble and insoluble iron. The soluble iron in kaolin can be obtained by leaching with hydrochloric acid, while the total iron is achieved by calcining with sodium hydroxide. The content of insoluble iron is equal to the content of total iron minus soluble iron. The phenanthroline spectrophotometry method is used to determine the content of iron. The relative standard deviation of this method is less than 5%, and sample recoveries range from 95% to 105%. The detection limit of iron is 1.06 μg/g. Other elements in kaolin did not interfere with iron determination by this method. Soluble iron was almost free iron with little structural iron in kaolin. The maximum content of removal iron for the whitening technique can be estimated by quantitative analysis of soluble iron in kaolin.
