In the present study, the synthesis, characterization of nanocomposites based on poly (methacrylic acid) (P-MAA / MWCNT) and poly (4-vinylpyridine) (P-4VP /MWCNT) and their use for sequential preconcentration of Cr (III) and Cr (VI), respectively, with further on-line determination by FAAS was evaluated.
