The Determination of Iron Content in High Aluminium Zinc Alloy By the Method of 1,10—Phenanthroline

用１，１０———二氮菲法测定高铝锌合金中铁的含量，提出用分取试液与所加试剂液酸度差异的互补性，达到显色所要求的酸度。简化了操作过程，净化了操作环境。验证实验表明，所测结果准确度高、精密度好。

In this paper, a method of 1,10—phenanthroline to determine the iron content in high aluminium zinc alloy was introduced. In order to meet the need of the acidity for development the acidity difference complementarity was used which was performed by taking part of reagent and then adjusting the residu reagent. This method simplifies the process of operation and purifies the enviroment of operation. The proved experiments show that the results of analysis are in high accuracy and good precision.
