摘要
比较了8 羟基喹啉(8 Ox)在ETAAS和ETV ICP AES中的基体改进作用。结果表明:在ETAAS中,8 Ox无论是对Cr(Ⅲ)还是对Cr(Ⅵ)都表现出良好的化学改进作用。而在ETV AES中,8 Ox只对Cr(Ⅲ)有化学改进作用,借此可实现Cr(Ⅲ)和Cr(Ⅵ)的原位分离。
The chemical modification of 8-Ox for the determination of trace Cr(Ⅲ) and Cr(Ⅵ) by ETAAS and ETV-ICP-AES was comparatively studied.The conditions for in-situ separation of Cr(Ⅲ) and Cr(Ⅵ) in both ETAAS and ETV-ICP-AES were investigated,and the different results obtained for ETAAS and ETV-ICP-AES were explained with the result of differential thermal analysis.
