Advancing lithium recovery from brine through highly selective membrane-capacitive deionization (M-CDI) and real-time monitoring using miniature solid-state lithium sensors
Abstract
In the 21st century, two pivotal requirements for lithium recovery should be met: 1) lithium recovery from brine and 2) real-time in-situ lithium concentration monitoring. This study develops a state-of-the-art polyelectrolyte multilayer ion selective membrane (PEM-ISM) sensor focusing lithium in the brine. The mm-sized S-ISM sensors were made by precisely electrospraying a well-mixed lithium ionophore cocktail matrix and then dipping deposition polycation (Poly(allylamine hydrochloride) and polyanion (poly(sodium 4-styrenesulfonate)) for enhanced adhesion and stable structure onto the electrode surface. And also, PEM-ISM sensor was incorporated with M-CDI for the first time to record the lithium concentration changes with adsorption/desorption cycles. Tests results indicated that PEM-ISM sensors possessed excellent selectivity, accuracy, and stability to record the lithium concentrations. In summary, the integration of novel Li sensor with M-CDI has a great potential to advance Li recovery from brine wastewater and determine the maximum capacity of M-CDI, and ultimately elevate lithium recovery efficiency.
