摘要
本文从理论上分析了互扩散法和电导法测定反离子通过离子交换膜的自扩散系数,用这二种方法测定了Cu2+和H+通过聚苯醚均相阳膜的自扩散系数,对所得的结果进行了比较和验证。
This paper theoretically derived the equations for calculation of self diffusion coefficients of counter ions with unequal valence throuth a cation exchange membrane by conductivity or inter diffusion, respectively.The HCl-CuCl 2 system was experimentally studied by using a Poly(phenylene Oxide) polymer cation membrane. The self diffusion coefficients of Cu 2+ and H + were determined by these two methods and compared with each other. The results showed a good coincidence between them.
