In this paper several fluorine-containing matrix modifiers have been tested for ETV-ICP-AES determination of elements with different volatility, such as refractory element Ti, medium volatile element Ni and easily volatile element Pb.

• 本文探讨了电热蒸发-电感耦会等离子体原子发射光谱法（ETV－ICP－AES）测定不同挥发性元素Ti、Ni和Pb时含氟基体改进剂的改进作用。
