摘要
The sorption of ion pairs formed by cationic surfactants of alkyltrimethylammonium and alkylpyridinium families and sulfophthalein dyes on polyurethane foams is studied as a function of their type and the structure of the surfactants and dyes. A highly efficient procedure for the sorption-photometric determination of cetyltrimethylammonium bromide is developed.
