摘　　要：用盐酸溶解乙二醇锑(EG),然后加入适量的酒石酸钾钠络合锑,用乙酸钠控制溶液酸度,盐酸羟胺还原亚铁离子,以邻二氮杂菲为显色剂,建立了一个测定乙二醇锑中铁含量的目视比色法。结果表明:该方法操作简单、准确可靠。Dissolve glycol antimony in hydrochloric acid,by adding an appropriate amount of potassium sodium tartrate complexed with antimony,sodium acetate is used to control the acidity of the solution,and reduction of ferrous irons with hydroxylamine hydrochloride,phenanthroline is used as the developer,a visual colorimetry method for the determination of iron in ethylene glycol atimony was established.The result showed that the method was simple and accurate.
