Functionalization of tannic acid and campesterol with polyelectrolyte multilayer membranes for lithium ions separation and recycling

The potential use of chitosan/poly(styrene sulfonate) (CHS/PSS) polyelectrolyte multilayer (PEM) membranes functionalized with tannic acid (TA) and campesterol (CHT) for efficient separation and recycling of lithium from aqueous matrix under ultrafiltration conditions are examined. The PEM assembled...
