[Study on the analysis of main and trace elements in phosphate rock by ICP-AES].
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.
