摘要：

The dependence of sorption of 4-nitrophenylazoderivatives of phenols and naphthols by polyurethane foams (PUF) (on the basis of ethers and esters) has been studied as the function of PUF type, 4-nitropbcnyldiazonium tetrafluoroborate concentration, nature and concentration of counter cations and analyzed sample volume. It has been shown that sorption increases in the presence of salts of alkali metals and cationic surfactants. Some estimation of sorption mechanism has been made. Sorption-photometric method for the determination of aromatic hydroxycompounds has been developed. It is characterized by low detection limit.
