Sorption of nitrophenol from water media by
polymeric sorbents based on n-vinylpyrrolidone
Abstract
In static conditions, the sorption of
nitrophenols on polymeric sorbents, based on N-pyrrolidone, has been studied.
The constants and energy characteristics of sorption are calculated, the
mechanism of sorption of nitrophenols is established. Correlation dependencies
between the distribution coefficients of nitrophenols and hydrophobicity of
sorbates are established. The contribution of hydrophobic and specific
interactions to sorption mechanism is substantiated. Based on the results
obtained, the polymers studied are recommended for the concentration and
extraction of nitrophenols from aqueous solutions.
Key words: nitrophenol, sorption, polymeric
sorbent, N-vinylpyrrolidone.
