用盐酸消解不适用于石墨炉的测定？

谁说不能用盐酸呢？可以用啊。应该是避免使用硫酸和磷酸。
不过测铝时不用盐酸，因为氯化铝挥发性强。

ASTM 标准中原文：
Total recoverable iron is determined following acid digestion and filtration. Because chlorides interfere with furnace procedures for some metals, the use of hydrochloric acid in any digestion or solubilization step is to be avoided.
