Rossin Professor in the departments of civil and environmental engineering and chemical engineering at Lehigh University, has written a book, "Ion Exchange in Environmental Processes: Fundamentals, Applications and Sustainable Technology," published by John Wiley & Sons, Inc. in September 2017.

The book - 475 pages in eight chapters - aims to provide a comprehensive introduction to ion exchange for beginners as well as an in-depth coverage of the latest advances for those already in the profession.

"Ion exchange is a fascinating scientific field," SenGupta writes in the preface, "and as central to natural and biological systems as it is to engineered processes.

"The intrinsic complexity of the field was poorly understood and the science of ion exchange was accepted as mere exchange of ions."

"I am quite optimistic," continues SenGupta, "that the science, technology and materials related to ion exchange, as presented here, will help fill some void and create new synergy for the next generation of innovators and inventors in the field."

SenGupta's altruistic approach to his profession extends far beyond the research lab.
