It can be concluded that good separation of both co-ions and counter ions cannot be achieved by a single type of the singly charged NF membranes. 总体上讲,采用单一的荷电纳滤膜是不能同时取得同名离子之间和反离子之间的高效分离的。
The sensitivity for the determination of tantalum could be increased several times, a lot of co-ions would not disturb the determination of tantalum after separation and preconcentration. 经分离后,钽的测定灵敏度可提高数倍,大量共存离子不干扰钽的测定。
When the counter-ions were the same, the size and hydrability of co-ions also had effects on diffusion coefficient. 当反离子相同时,同离子的尺寸和水化性也会对扩散系数产生影响。
The shielding effect of the co-ions in adsorption phase on the electrostatic interaction among protein molecules and adsorbents increases with an increase of ionic strength. 随着离子强度增高,吸附相伴离子对蛋白质与吸附剂之间和蛋白质分子间静电力的屏蔽作用增大。
