| Abstract: | the abundant sample and nitric acid sample dissolving were adopted in the paper,then excess EDTA was added and titrated by zinc acetate acid in pH≈5.8, Aluminum EDTA complex was released after adding of ammonium fluoride.,then released EDTA was titrated by zinc acetic acid. The method was simple,rapid and accurate,it can be used to determine the aluminium in zinc alloy. |
