摘要：

The selectivity and characteristics of a direct contact membrane distillation type experiment were studied by using dried fine porous membranes, such as poly (vinylidene fluoride) (PVDF) hollow fibers. Some coating materials and heat treatment of the PVDF membrane increased the selectivity and yielded selectivity higher than the corresponding relative volatility. Marked asymmetric permeation was observed for the various membranes.
