Conteúdo: |
The interaction between poly(o-ethoxyaniline) (POEA) adsorbed onto solid substrates and humic substances (HS) and Cu2+ ions has been investigated with UV-VIS. Spectroscopy and atomic force microscopy. Both HS and Cu2+ cause the POEA film to be further doped, and alter the film morphology. This interaction was exploited in a sensor array made of nanostructured films of POEA, sulfinated lignin and HS, which could detect small concentration of HS and Cu2+ in water. |
