Wastewater treatment facilities cannot remove high levels of cations found in the millions of gallons of produced water from hydraulic fracturing drilling in the Marcellus Shale region. Other current disposal methods, including ion exchange and evaporation, are too costly or inefficient to address the quantity of produced water, thus a new purification method must be developed. This research explores the ability of pyridine based compounds to extract barium, and other cations commonly found in high levels of hydraulic fracturing produced water, from aqueous solution.
