| 摘 要： | 采用HNO3-HF—HClO4混酸溶样后，直接用ICP—AES法快速测定磷矿中氧化锶含量。该法在选定Sr的分析线为407．771nm处干扰很小，检出限为0．0012μg／mL，相对标准偏差为0．79％，具有抗干扰能力强、线性范围宽、精密度高、结果准确等特点。

| Abstract: | By dissolving sample with the mixed acid HNO3-HF-HC1O4, the mass fraction of strontium oxide in phosphate rock is rapidly determined by ICP-AES. The method has few interference with the analysis Line of 407.771 nm, the detection limit of method is 0.001 2 μg/mL, the relative standard deviation is 0.79%. This method has the strong anti-interference, wide linear range, high accuracy, accurate result etc. |
