CGNIES Researchers Undergo Potentiostat Training to Advance Sustainable Metal Recovery
Researchers from the Center of Green Nanotechnology Innovations for Environmental Solutions (CGNIES), together with Chemical Engineering faculty members and students from the University of Mindanao, took part in an intensive training on the operation and maintenance of the Metrohm Potentiostat System last October 20-21, 2025 at the CGNIES Laboratory, Innovation Complex. The session was facilitated by Ms. Nichole Ramos (Applications Chemist) and Mr. Aaron Joshua Lozano (Service Engineer) from Kimika Solutions Corp.
The training introduced participants to the fundamental theories and electrochemical principles behind potentiostat operation, focusing on its key components, configurations, and core functions such as cyclic voltammetry (CV) and chronoamperometry. Participants engaged in hands-on exercises, including electrode setup, test execution, and electrochemical data interpretation, gaining valuable experience in applying the instrument to real-world research contexts.
The Potentiostat System serves as a core analytical instrument in the MetaEco Project, enabling precise control and monitoring of electrochemical reactions vital for the sustainable recovery of valuable metals such as lithium (Li), nickel (Ni), cobalt (Co), and manganese (Mn) from spent electric vehicle (EV) batteries. Its use ensures accurate validation of electrode performance and optimization of reaction parameters, contributing to the development of a continuous electrochemical system that supports green and efficient metal recovery.
