Description

The method is developed for investigation of kinetics of nonequilibrium extraction processes for multicomponent systems. The Pr-Nd-NaNO3-YNO3-TBP-kerosene system is takes as example. Unique experimental plant is created for kinetic investigation, wherein measurement of kinetic dependences is based on the use of spectrophotometers of UV-visible spectrum and running cuvettes. Computer software for decoding of multicomponent system spectra is developed

Abstract (Russian)

Разработана методика исследования кинетики неравновесных экстракционных процессов для многокомпонентных систем на примере системы Pr-Nd-NaNO3-YNO3-TBP-керосин. Для иследования кинетики создана уникальная экспериментальная установка, в которой измерение кинетических зависимостей основано на использовании спектрофотометров УФ-видимого спектра и проточных кювет. Разработано програмное обеспечение для расшифровки спектров многокомпонентных систем
