Join us for the first lecture of the 2019 Busse Lecture Series on March 28 at 3:30pm in Rennebohm Hall, room 2006. Professor Dale Wurster from the University of Iowa College of Pharmacy and Department of Pharmaceutical Sciences and Experimental Therapeutics will present his research about activated carbon adsorption site specificity.
Activated carbon is used in methane and hydrogen storage, air purification, decaffeination, gold purification, metal extraction, water purification, sewage treatment, air filters in gas masks and respirators, filters for compressed air, and, of course, as an aid in the detoxification of drug overdose. In spite of activated carbon’s widespread use, there is little understanding of the operative adsorption mechanisms. Wurster’s research demonstrates that there is adsorption site specificity on the activated-carbon surface, and that site-specific adsorption is driven by the change in enthalpy. Hid research also shows that, in aqueous media, there is a non-site-specific adsorption process which is driven by the change in entropy. Both mechanisms will be discussed.
