Ion Exchange in Environmental Processes

Arup K. SenGupta, PhD is the P.C. Rossin Professor in the Department of Civil and Environmental Engineering and Department of Chemical Engineering at Lehigh University. Over the last 35 years he has studied, learned, taught and conducted extensive research into nearly every facet of ion exchange. Dr. SenGupta is recognized as the inventor of hybrid ion exchange nanotechnology (HIX-Nano) that offers enhanced separation through the Donnan Membrane Principle. HIX-Nano materials are currently in use in six different countries including the USA to remove arsenic, fluoride and phosphate from contaminated water and waste water. In 2004, Dr. SenGupta received the International Ion Exchange Award at Cambridge University in England. He was the North American Editor of the Reactive and Functionalized Polymers Journal from 1996-2006.
