STUDY OF SORPTION OF Cu2+ IONS BY POLYAMPHOLYTIC FIBROUS ION EXCHANGES BASED ON «NITRON» FIBER
Abstract
In the work, by chemical modification of the local "Nitron" fiber, a fibrous ionite with polyampholyte properties was obtained. Its structure was determined by analyzing its IR spectra. The kinetics of static sorption of Cu2+ ions from aqueous solutions was studied spectrophotometrically, the main parameters of sorption were determined, and the thermodynamic functions of the process were calculated. In the dynamic method, it was determined that the exchange capacity of ionite for Cu2+ ions is maximum 320 mg/g.
