摘　　要：主要采用原子荧光法测定不同浓度的硼氢化钾溶液对硒标准溶液荧光强度的影响,实验结果表明,硒的荧光强度会随着硼氢化钾浓度的增大而降低,硼氢化钾质量浓度为0.01 g/mL时,能节省测定硒元素的成本和提高测定系统的分辨力。In this paper,atomic fluorescence method was used to determine the effect of potassium borohydride solution with different concentrations on the fluorescence intensity of selenium standard solution.The experimental results show that the fluorescence intensity of selenium decreases with the increase of potassium borohydride concentration.When the concentration of potassium borohydride is 0.01 g/mL,the cost of selenium determination can be saved and the resolution of the determination system can be improved.
