利用CL-TBP萃淋树脂分离基体铀,采用ICP-AES法测定铀水冶生产中的萃取原液、母液等一系列硫酸体系中的钛.选用元素最佳分析谱线和仪器合适的工作条件,方法的RSD＜ 10％,回收率在90％～109％之间.该方法快速、简便,满足分析要求.%Matrix uranium was separated by using CL-TBP levextrel resin and then ICP-AES method was used to determine titanium content in sulphuric acid system(such as feed solution and mother solution) in uranium hydrometallurgical process. Under the optimum element analysis spectral line and working conditions, the relative standard deviation of the method was less than 10% and the recovery rate was 90%-109%. The method is rapid,simple,and the requirement of the analysis can be met.
