Abstract
Amphotenc resins are synthesized by sulfonate of strong base resin. The influences of concentration of vitriol, reaction time and temperature on adsorption and desorption of amphoteric resins are studied. The optimum synthesis condition is achieved. The amphoteric resins prepared under these conditions exhibit good ability in water softening and their own regeneration.
