How can we calculate the Gibbs free energy on the membrane and water surface to indicate the membrane have the repulsive force to the salt?

I produce a positively charged membrane and have succesfully reject positively charged ions. In terms of charge effects, it may sound correct. But so far, only negatively charged membrane are...

For a negatively charged membrane for RO application, how is overall salt rejection heavily dependent on anion rejections?

Donnan potential is benefit in -vely charged membrane, where they can reject negatively charge ions (for example Cl-), and what happened to Na+ ions? Did it pass through? How about +vely charge...
