摘要
钼在盐酸羟胺存在下 ,与EDTA形成稳定配合物 ,铜盐返滴定 ,配位滴定法测定钼铁中的钼。试验表明 ,该测定方法缩短了分析周期 ,具有准确性和重现性均好的优点。
A method for the determination of molybdenum in the Mo-Fe alloy was proposed.After addition hydroxylamine Hcl,the complex compound was very steady,formed by molybdenum and EDTA.The surplus EDTA was titrated with copper standard solution.The context of molybdenum could be indirectly calculated.The method was simple and convenient.It cost less time than gravimetric method.The analytical results were satisfactory.
