Thermodynamics of nitrophenols sorption from aqueous media with N-vinylpyrrolidone-based polymer

Nitrophenols sorption with polymer material based on N -vinylpyrrolidone has been studied in the static conditions. The sorption constant and the basic thermodynamic parameters of sorption have been determined. The sorption occurs via non-specific physical interactions, it is so called “extraction sorption.” The prepared polymer material has been more efficient in nitrophenols sorption than silica.
