The charge density can also be affected by incorporating positive charge into the disulfide containing monomer, or by using imidate groups as the reactive portions of the disulfide containing monomer as imidates are transformed into amidines upon reaction with amine which retain the positive charge. ...
By adjusting the reaction conditions and the concentration and type of the reactive monomer, a loose composite layer with different spatial morphology is constructed on the surface of the membrane [12]. 4.2. Mechanism of the Membrane Preparation Process for Improving the Removal Rate of Non-...
creating a concentration difference on the feed solution side, which is known as brine or brine rejection. The pore size of reverse osmosis membranes is less than 1 nm, while the size of PFAS molecules is significantly bigger. The removal of long-chain PFAS for NF is estimated to be around...
