Research progress on nanofiltration separation mechanism models
Recently,nanofiltration membrane separation technology has been widely used in material separation and water treatment,and the understanding of nanofiltration membrane separation mechanism is the theoretical basis to accurately predict the separation performance of nanofiltration membrane.This paper reviews models used to interpret and predict nanofiltration separation performance from perspective of historical development,including irreversible thermodynamic model,structural models and other methods.The structural models involve the steric-hindrance pore model,the fixed charge model,space charge model,the electrostatic and steric-hindrance model,the Donnan steric pore model and dielectric exclusion.Then the models'characteristic,development and applications to analyze separation mechanism and predict separation performance are summarized.With the advancement of analytical instruments and computer technology,future research on NF separation mechanism and theory should focus on combining structural and artificial intelligence models to predict membrane separation performance and optimize the design of membrane materials for various complex NF separation systems in order to further promote the accurate construction of NF membranes and thus expand their application scenarios.
