Abstract: In this study, a copolymer, cyclodextrin/epichlorohydrin was synthesized and used as an adsorbent to remove two taste and odor causing compounds, namely, MIB and geosmin from the Lake Michigan water. The removal efficiency of these compounds using the copolymer on average was 74.5% for MIB and 77.5% for geosmin as compared to the removal efficiency using powdered activated carbon that resulted in 52.9% and 67% removal, respectively, for the same compounds. The removal efficiencies were examined for an initial concentration range of 20 to 120 μg/L for both MIB and geosmin.
