A weak base anion resin has alkylamine segments covalently bound to cross-linking segments, the alkylamine segments being selected from a group consisting of: vinylamine, N-methylvinylamine, N,N-dimethylvinylamine, N-methyl-N-ethylvinylamine, and N,N-diethylvinylamine, and the weak base anion resin including ions adsorbed to the alkylamine segments. A method for ion exchange includes providing a weak base anion resin, contacting the weak base anion resin with a solution containing ions to one of capture or adsorb ions from solution to the weak base anion resin, and regenerating the weak base anion resin. A method to capture and release an acid gas includes providing a weak base anion resin, contacting the weak base anion resin with a gas including an acid gas to one of capture or adsorb the acid gas from the gas to the weak base anion resin, and regenerating the weak base anion resin to release the acid gas.
