Abstract
A new method of extraction preconcentration was proposed for flow analysis. Preconcentration was performed on an extraction-chromatography column; the concentrate was eluted with the extractant and then separated from the aqu eous phase using a chromatomembrane cell. The capabilities of the method pr oposed were shown using the flow-injection determination of petroleum produ cts in natural water as an example.
