| 摘要: |
| 利用酸性介质中钼(Ⅵ)对硫酸肼-金莲橙Ⅳ体系缓慢反应的催化作用,以氢氧化钠溶液中止反应,建立了一个动力学示波极谱测定钼的新方法。方法的线性范围为0.01μg/mL~0.2μg/mL,已用于钢样中痕量钼的测定,结果满意。 |

| Abstract: |
| In acidic medium, Mo (Ⅵ) has strong catalytic effect on the slow redox reaction of (NH2NH2)2SO4 and methyl orange Ⅳ, and the catalytic reaction can be quenched with NaOH solution based on the experimental facts, a new catalytic oscillopolarographic method determining 0.01μg/mL-0.2μg/mL Mo(Ⅵ) has been proposed. The method has been applied to the determination of ultrace amounts of molybdenum in steel sample with satifactory results. |
