Study of the Effect of the "Third" Component on the Sorption of Elements in the System Chelating Sorbent-Element- para -Substituted Anilines

Sorption methods using polymer chelating sorbents, which contain functional analytical groups and exhibit chelating properties, are highly promising for the extraction and preconcentration of traces of metals at high concentrations of matrix elements. We synthesized a new class of polymer chelating sorbents based on aminopolystyrene and bisazo derivatives of resorcinol corresponding to the structural formula
