ICP AES is employed to determine multi elements in rocks. The samples are digested by mixtures of HNO 3/HF/HClO 4 and the residue is treated with 5% HNO 3. The solutions are subsequently analyzed by SPECTRO model ICP AES with satisfactory results.

• 探讨了用ICP－AES法同时测定岩石中的多种元素，样品经过HNO3/HF/HClO4混合酸消解，残渣用5%25HNO3溶解后测定，获得满意结果。
