"Towards the Scalable Manufacturing of Nitrate Ion-Selective Electrodes"



By
M. Ramazan Oduncu
Purdue MSE Ph.D. Preliminary Exam

Advisors: Professor Alexander Wei and Professor Mukerrem Cakmak



ABSTRACT


Ion-selective electrodes (ISEs) are from electrochemical sensors family with the longest history of more than 90 years and the most common application of chemical sensors. ISEs applications have been routinely used as an analytical technique in various fields such as process control, clinical and environmental analysis and physiology. The history of ISEs has begun with the invention of pH electrodes by Haber and Klemensienwicz. Then, these electrodes have been used more frequently after glass pH electrodes and pH meters haven been manufactured commercially in late 1930s.
Analysis via ISEs is advantageous since it does not require any sample pretreatment and it provides the opportunity of continuous monitoring in environmental, clinical and industrial applications. Polymeric membrane based ISEs comprised of neutral or charged carriers (ionophores) are able to detect a large number of inorganic and organic ions. Starting early 2000s, ISEs chemical sensing capabilities have evolved because of the improvement in lower detection limit, new sensing concepts and materials, and deeper understanding in theory of potentiometric response. This seminar will cover the components of ISEs, potentiometric response of a sensor and fabrication of a solid-contact, ion-exchanger based NO3-(nitrate) ion selective membrane onto ink-jet printed Ag electrodes. Then, the route to scalable manufacturing (roll-to-roll (R2R) manufacturing) of ISEs will be discussed.
