主　　题：cerium neodymium nanofiltration Spiegler-Kedem model 

摘      要：Lanthanides are widely used in various commercial applications, which results in public exposure to them, and it is a matter of concern. Many methods were used to remove lanthanides from wastewaters generated from their commercial use. In the present work, nanofiltration membrane process was used to remove the cerium and neodymium from their respective feed solutions. The feed and permeates were analyzed for solute concentration by inductively coupled plasma-atomic emission spectroscopy. Irreversible thermodynamics Spiegler-Kedem model, in combination with the film theory, was used to estimate the membrane transport parameters, viz., reflection coefficient of membrane and solute permeability, and mass transfer coefficient to study their dependence on feed solute concentration.
