| 摘 要： | 铀是一种重要的自然资源,在多个领域都有广泛的用途,所以检测铀也变得越来越有意义。建立了一种操作简单,价格低廉,灵敏度高的检测方法,首先将Salophen与铀酰结合成Uranyl-Salophen配合物,接着采用十二烷基硫酸钠(SDS)表面活性剂将配合物包裹,从而达到增敏检测U(VI)的目的。优化了时间、温度、SDS剂量、pH条件,在最优条件下荧光强度与铀的浓度范围在0.005～3.5 mol/m L下呈现良好的线性关系,在实际样品中检测铀的回收率在96%～103%。

| Abstract: | Uranium is an important natural resource and is widely used in many fields,so it is becoming more and more meaningful to detection of uranium.In this paper,a simple operation,low cost and high sensitivity detection of method was established.Firstly,the Uranyl-Salophen complex was formed by the combination of Salophe with uranyl.And then detect U(VI) effectively by adding sodium dodecyl sulfonate(SDS) to the above substances.It optimized the time,temperature,SDS concentration,pH condition.The fluorescence intensity and the range of uranium concentration showed a good linear relationship during 0.005~3.5 mol/mL under the optimal conditions.This method can be used in the detection of practical samples and the recovery rate was 96%~103%. |
