A comparative study on Cu 2+ removal by shallow shell resin (Purolite SST 60) and traditional strongly acidic cation exchange resin (Purolite PFC 100) was performed. Batch experiments were carried out as a function of  resin  dosage and  solution pH and contact time. Ion exchange reaction showed a pH depended feature.  Maximum removal of Cu 2+ achieved  pH  from 2 to 5. Sorption isothermal data is well interpreted by the Langmuir equation. Additionally, kinetic experiments showed that the pseudo first-order model was suitable for such resins. The regeneration performance of shallow shell technology (SST) resin is better than PFC 100.  A solution of 2M H2SO4 performed well in regenerationof SST 60 resin. On the other han maximum regeneration reached 80% for PFC 100 resin. Ozet: Bu calismada, klasik iyon degistirici recine (Purolite PFC 100) ve  sig kabuk  recine (Purolite SST 60)  ile Cu 2+ giderilmesi incelenmistir. Yapilan kesikli calismalarla Cu2+ giderilmesine, recine miktari, cozelti pH`i ve temas suresinin etkisi incelenmistir. Cozelti pH`inin 2 ile 5 arasinda oldugu durumda Cu2+ iyonlari tamamen giderilmistir. Denge calismalarinda elde edilen sonuclar Langmuir izoterm modeline daha uygun olmustur. Kinetik calismalarda elde edilen sonuclar yalanci birinci mertebe kinetik modeline uygunluk gostermisir. SST 60 recinesinin rejenerasyon verimi PFC 100 recinesinden daha yuksektir. 2M H 2 SO 4 ile SST 60 recinesi tamamen rejenere edilmistir.
