Selectivity of artificial water channel-polyamide composite membranes towards inorganic contaminants

Effective separation of dyes/salts by sulfonated covalent organic framework membranes based on phenolamine network conditioning

“…This phenomenon is primarily due to the larger diameter of divalent hydrated SO 4 2− ions compared to monovalent hydrated Cl − ions, as well as the greater negative charge of SO 4 2− over Cl − . 48 These separation results indicate that the modied membrane can effectively retain dyes while allowing some inorganic salts to pass through. Separation of dyes from two components.…”
