Micropollutants migration from ion-exchange resins into water

Water samples collected at different stages of a demineralization process w ere examined after closed loop stripping and analysed by GC-FID and CC-MS. The results showed a contamination arising from the contact with ion-exchan ge resins. The quantity and the type of pollutants were different depending upon the resin bed, cationic or anionic exchanger, but all the examined sa mples exceeded the limits set according to the normative for the human cons umption water for various classes of compounds: Alkylparaffns, alkylbenzene s, alkyltoluenes, aromatic chloro-, and bromoderivatives.
