摘要：

A method has been developed for the simultaneous determination of eight divalent metal ions based on solid-phase extraction and separation on a dynamically coated C18 reversed-phase high-performance liquid chromatography column. The method has been applied to the determination of these metal ions in some anaerobic sealant formulations, with limits of detection as low as 30 ppb for certain metal ions. It has been shown that this approach is capable of distinguishing between free and complexed metal ions in such matrices.
