| 摘要: |
| 优化电感耦合等离子体-原子发射光谱法(ICP-AES)仪器工作条件,建立一种快速、准确、实用的肥料中金属元素测定的方法,并用该方法测定微量元素叶面肥料样品中的砷、铅、镉、铬、镍、铁、镁、钙、锌9种金属元素含量。该方法通过硝酸-高氯酸消解体系,有效彻底地消解了微量元素叶面肥料样品,而且对易挥发的砷、铅的保留效果比较理想。该方法的精密度高、检出限低,样品回收率90%~106%,精密度(RSD)均小于10%,说明方法简单、精确、快速、使用试剂少,能够有效地克服常规分析方法操作手续繁杂,分析灵敏度低等缺点。 |

| Abstract: |
| A simple,fast,accurate and sensitive method was established to determine the metal element in fertilizer by ICP-AES.By HNO3 and HClO4,samples were completely digested.Nine elements such as As,Pb,Cr,Ni,Ca,Cd,Fe,Mg and Zn were simultaneously determined.By optimizing experimental conditions,RSD of the method is under 10% with the recovery of standard addition being 90%~106%. |
