Сорбция перренат-ионов аминополимерами и их функциональными производными

Abstract

The sorption properties of new amino polymers and their functional derivatives with re-spect to perrhenate ions in an acidic environment were studied. The objects of study were N-(2-pyridylmethyl)polyallylamine (PMPAA), N-(2-pyridylmethyl)polyethylenimine (PMPEI), as well as imidazolylmethylated derivatives of polyallylamine (IMPAA), polyethyleneimine (IMPEI) and polyamylstyrene (IMPAS). The optimum pH values of solutions for sorption were determined experimentally. The adsorption process was described by the Langmuir, Freindlich, Thoth, Dubinin-Radushkevich equations. The high sorption rate of perrhenate ions on the studied functional derivatives of aminopolymers was established.
