Abstract Details

2016, Master of Science, University of Akron, Polymer Science.
Sustainability is an inherent parameter when considering chemical processes and usage. Fossil fuel-fired power plants are synonymous with greenhouse gas (GHG) emissions. GHGs are attributed to climate change and global warming. In the U.S. alone over 50% of GHG emissions were attributed to transportation and electricity generation of which 82% compromised carbon dioxide (CO2). Significant efforts have been focused on the development of solid sorbents containing amine or polyamine material for reversible adsorption-desorption of CO2 as means of controlling CO2 emissions. Previous work in the Chuang group has addressed the issue of understanding the fundamental adsorption interactions between CO2 and amine-based solid sorbents. Additionally there is interest in whether such amine-based materials could be applicable in alternative technologies. Use of rare earth (RE) materials are omnipresent from electronics such as phones to catalysis and optics. Unfortunately their end-of-life recovery is not mainstreamed and is complicated by the fact that RE are present in small quantities often intermixed with other various metals. The scope of this thesis was two-fold: to investigate the feasibility of using commercial polyamines for (i) CO2 sequestration in comparison to lab-made sorbents and (ii) RE recovery from aqueous solution using lanthanum as the model ion. Separately, the effects of epoxy and polyamines ratios on CO2 capture capacity and perceived mechanical integrity were investigated through a theoretical model with relation to chain extension and crosslinking.
