研究了经γ射线辐照后的尼龙6接枝丙烯酰胺（AM）和丙烯酸（AA）膜对尿素和氯化钾的渗透性能。尿素和氯化钾通过AM和AA接枝膜的渗透性随着接枝水平的增加而增加。尿素和氯化钾通过AA和AM接枝膜（接枝率超过100%）的扩散可以用自由体积概念来解释。然而，这种解释不适用于渗透AA接枝膜的氯化钾。氯化钾通过高度溶胀的AA接枝膜的扩散服从自由体积的概念向外，但扩散的浓度依赖性的渗透修改。
The permeability of urea and potassium chloride through γ-irradiated nylon-6 membranes grafted with acrylamide (AM) and acrylic acid (AA) was investigated. The permeability of urea and potassium chloride through both AM and AA grafted membranes increased with increases in the levels of grafting. The diffusion of urea and potassium chloride through AA and AM grafted membranes (with more than 100% grafting) can be explained by the free volume concept. However, this explanation does not apply to potassium chloride permeating through AA-grafted membranes. The diffusion of potassium chloride through highly swollen AA-grafted membrane obeys the free volume concept outwardly, however the diffusion is modified by the concentration dependence of the permeant.
