Pantaleao, Ines; Portugal, Ana F.; Mendes, Adelio; Gabriel, Joaquim – Journal of Chemical Education, 2010
A pedagogical experiment is described to examine the physical absorption of gases, in this case carbon dioxide, in a hollow fiber membrane contactor (HFMC) where the absorption concentration profile can be followed by a color change. The HFMC is used to teach important concepts and can be used in interesting applications for students, such as…
