MEMBRANES |
摘要 |
<p>Mixed matrix pervaporation membranes are described which include i) a matrix phase comprising a polymeric material, and ii) a zeolitic imidazolate framework (ZIF) dispersed in the matrix phase. In membranes described, the thickness of the membrane is greater than 0.5μm. The membranes may in examples be used in a process for separating an organic compound from an aqueous liquid mixture. An example process includes contacting the liquid mixture on one side of a mixed matrix pervaporation membrane to cause the organic compound to permeate the mixed matrix membrane, and removing from the other side of the membrane a permeate composition comprising a portion of the organic compound which permeated the membrane. Example membranes described have relatively good selectivity for separation of the organic compound from the liquid mixture.</p> |
