Project Description and Objectives:

Nanofiltration (NF) is a kind of precise membrane separation process under low pressure conditions. It has high retention efficiency for multivalent ions and organic small molecules (150-2000Da). In our previous study, Metal-polyphenol nanofiltration membranes were prepared by a layer by layer (LBL) method and spin-LBL method on PES membranes. The membranes prepared by a spin-LBL method showed higher rejections to dyes and water permeability than those of LBL method. However, mechanisms of the difference in separation and rejection performance between the two membranes still need to be investigated.

Eligibility Requirements:

Major in environmental engineering, chemical engineering, polymer or other related areas.

Motivation to work.

Experience with the computational method of molecular modeling is preferred.

Main Tasks:

Mechanism analysis of the difference in separation and rejection performance.
