Abstract

|
|
Ion exchange performence to remove nitrate in water studied using commercially available strong vase anin exchange resin of Cl$^{-}$ type in the batch reactors. Anion exchange resin was more effective than activated carbon or zeolite. With large resin amount or high temperature or low initial concentration, nitrate removal characteristics for a typical gel-type resin was increased. The curves showed the generally accepted selectivity sequence as SO$_{4}$$^{2-}$>NO$_{3}$$^{-}$>NO_{2-}>HCO$_{3}$$^{-}$.
