摘要
利用二氯乙烷萃取邻二氮菲-铁(Ⅱ)-苦味酸盐三元配合物,可以藉分光光度法测定钛氧化物中的微量铁,表观摩尔吸光系数达1.22×105。方法灵敏、干扰少,已用于高纯钛氧化物中微量铁的测定。
After extracting the three-component complex-o-phenanthroline-Fe(Ⅱ)-picrate by 1,2-dichloroethane microgram iron in titanium oxide could be determied by spectrophotometry. Its apparant molar absorption coefficient was 1.22×105. This method, more sensitive and less interferential, has been used to analyze the iron content in high purity titanium oxides.
