Abstract
The interaction between poly(o-ethoxyaniline) (POEA) adsorbed onto solid substrates and humic substances (HS) and Cu2+ ions has been investigated using UV–vis spectroscopy and atomic force microscopy (AFM). Both HS and Cu2+ are able to dope POEA and change film morphology. This interaction was exploited in a sensor array made with nanostructured films of POEA, sulfonated lignin and HS, which could detect small concentrations of HS and Cu2+ in water.
