题 目：Facilitated Transport Membranes for Energy and Biochemical Applications
摘 要：
The presentation covers recent advances in two types of facilitated transport membranes: (1) carbon dioxide-selective membranes for CO2 separation andhydrogen purification for fuel cells and (2) supported liquid membranes (SLMs) with strip dispersion for the recovery of antibiotics from aqueous solutions. We have synthesized carbon dioxide-selective membranes by incorporating amino groups into polymer networks for hydrogen purification for fuel cells. The membranes have shown high carbon dioxide permeability and selectivity vs. hydrogen, carbon monoxide and nitrogen up to 180oC. On SLMs, their stability has been ensured by a modified SLM with strip dispersion, where the aqueous strip solution is dispersed in the organic membrane solution. The SLMs have potential for extraction and recovery of antibiotics and biochemicals from fermentation broths and aqueous solutions. For example, Cephalexin has been extracted and concentrated; typical results have shown > 99% extraction and high recovery rates of 96 – 98%. Results showed that Cephalexin can be recovered from the mixture in conjunction with complexation without enzyme deactivation, which commonly occurs when complexation is conducted in enzymatic reaction mixtures.
