摘要
用ＨＦ－ＨＮＯ３－ＨＣｌ－Ｈ３ＰＯ４混合酸分解样品，在氨性条件下，以元素的磷酸盐沉淀分离样品中大量的Ｆｅ、Ａｌ、Ｃａ、Ｍｇ等基体元素，然后用ＩＣＰ－ＡＥＳ法测定，可用于地质样品中硼的分析。
The geological samples are decomposed by mixture of HF HNO 3 HCl H 3PO 4.The ions of iron,aluminum,calcium,magnesium, and the like are separated by phosphate precipitation in an ammonia solution. Boron in geological samples is determined by ICP AES with a satisfactory result.
