Composite semipermeable membrane |
| abstract |
There are provided a composite semipermeable membrane including a porous support membrane made of a substrate and a porous support layer and a polyamide separation-functional layer disposed on the porous support layer, wherein the zeta potential of the separation-functional layer at pH 6 is -20 mV or lower, and the zeta potential difference between potentials of the separation-functional layer at pH 10 and pH 3 is 25 mV or smaller, and a production method of a composite semipermeable membrane having high water permeability and high salt rejection performance and having high acid/alkali durability. |
