Abstract
A flow system including an on-line coated capillary column for the determination of traces of metal ions in natural waters is proposed, employing a manifold of flow microwave sample processing. This method eliminates the noise caused by the organic matrix, i.e. humic and fulvic acids. The system was applied to the determination of Pb, Co, Mn(II), and Fe(III) in swamp water. The proposed technique can be useful for routine analysis of natural and waste waters.
