Currently, the quantitative analysis methods for uranium that are widely used in laboratories, such as the volumetric method and inductively coupled plasma mass spectrometry (ICP-MS) cannot achieve low cost, simple operation, and little influence by other elements. The inductively coupled plasma optical emission spectrometer (ICP-OES) has a wide linear range, and high stability, and can be used to identify multiple elements simultaneously. However, when ICP-OES is used for quantitative analysis of uranium, the settings for the RF power, nebulizer flow, and pump rate can affect the analysis results. In this work, these parameters were carefully optimized for identifying uranium. Based on experiments, we selected two spectrum peaks 409.014 nm and 424.167 nm for quantitative analysis with the lowest interference. The optimal parameters obtained are atomizer flow rate of 0.75 L/min, a sample pumping rate of 1.6 mL/min, and a high-frequency power of 1400 W. Then we compared the accuracy of the volumetric method, ICP-MS method and ICP-OES method with the optimized parameter for analysis of experimental samples and references. The results showed that the ICP-OES with the optimized parameters proposed in this paper can be used to perform a convenient, quick, and efficient quantitative analysis of uranium in minerals.

当前，在实验室中广泛使用的铀定量分析方法，例如体积法和电感耦合等离子体质谱法（ICP-MS）不能实现低成本，简单操作以及受其他元素影响很小的目的。电感耦合等离子体发射光谱仪（ICP-OES）具有宽线性范围和高稳定性，可用于同时识别多个元素。但是，将ICP-OES用于铀的定量分析时，RF功率，雾化器流量和泵速的设置会影响分析结果。在这项工作中，对这些参数进行了仔细的优化以识别铀。根据实验，我们选择了409.014 nm和424.167 nm的两个光谱峰进行最低干扰的定量分析。获得的最佳参数是雾化器流速为0.75 L / min，样品泵送速度为1.6 mL / min，高频功率为1400W。然后，我们比较了体积法，ICP-MS法和ICP法的准确性具有优化参数的-OES方法，用于分析实验样品和参考。结果表明，本文提出的具有优化参数的ICP-OES可用于进行方便，快速，有效的矿物中铀定量分析。
