Abstract

Through studying the analysis of main and trace elements in phosphate rock, a method is proposed to determine main and trace elements (total 9 elements) in phosphate rock by ICP-AES method with sample dissolved by HF-HClO4. Detected limit is 0.0024-0.36 microgram.mL-1 and RSD is 0.75%-2.57%. This method is suitable for analysis of phosphate rock.

摘要

通过对磷矿石中主、微量元素的分析研究，提出了采用氢氟酸-高氯酸溶解样品，用ICP-AES法测定磷矿石中主、微量元素（共9种元素）的方法。检出限为0.0024～0.36μg·mL-1，相对标准偏差为0.75%～2.57%。该方法适用于磷矿石的分析。
