摘要
本文采用称大样和用硝酸溶样,然后加入过量的EDTA,在pH≈5.8时用乙酸锌滴定过量的EDTA,加入氟化铵,释放出与铝络合的EDTA,再用乙酸锌滴定被释放出的EDTA。该方法简单、快速、准确,适用于锌合金中铝量的测定。
the abundant sample and nitric acid sample dissolving were adopted in the paper,then excess EDTA was added and fitrated 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.
