测定微量铁的新方法

Novel Determination Method to Trace Iron

在对波长、显色剂用量、溶液酸度、显色温度和显色时间等方面进行了大量条件试验的基础上,建立了以铬天青S作显色剂的吸光光度法测定微量铁含量的方法.该方法简单适用,灵敏度高,选择性好.

On the basis of many condition experimentations to wavelength, amount of ingrain agent, solution acidity, ingraining temperature and ingraining time, a novel determination method to trace Iron has been developed by absorption photometry with chrome azurol S ingrain agent. This method is simple, suitable, sensitive and high selective.
