Microstructure Optimization of the MIP-177-LT Membrane for Highly Efficient Uranium Separation from Seawater

Although it has been valued as a major chemical separation technology to change the world, high-efficiency separation of UO22+ from seawater remains a pivotal challenge to date. In this study, we prepared a c-oriented MIP-177-LT membrane on a tubular substrate through epitaxial growth. Benefiting from 11 Å sized pores along the c axis, the rejection rate of UO22+ ions reached 98.3%, which was much higher than those of other metal ions (e.g., 4–6% for Na+, K+, Ca2+, and Mg2+; 41% for Fe3+). Through combination with 3 Å sized channels along the b axis, the water permeance reached as high as 63.4 L·m–2·h–1·bar–1, revealing great potential in practical uranium separation from seawater.

Abstract

Although it has been valued as a major chemical separation technology to change the world, high-efficiency separation of UO22+ from seawater remains a pivotal challenge to date. In this study, we prepared a c-oriented MIP-177-LT membrane on a tubular substrate through epitaxial growth. Benefiting from 11 Å sized pores along the c axis, the rejection rate of UO22+ ions reached 98.3%, which was much higher than those of other metal ions (e.g., 4–6% for Na+, K+, Ca2+, and Mg2+; 41% for Fe3+). Through combination with 3 Å sized channels along the b axis, the water permeance reached as high as 63.4 L·m–2·h–1·bar–1, revealing great potential in practical uranium separation from seawater.
