An investigation into the behavior of removing low molecular organics from polymer pellets in a countercurrent extraction column is presented. A mathematical model is developed, describing it in terms of intraparticle diffusion, adsorption, interphase equilibrium, convection and dispersion. The corresponding parameters are determined using nonlinear regression. The resulting partial differential equations are solved using a numerical method. The validity of the model is verified by means of experimental data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
