SHALLOW SHELL RESIN VERSUS TRADITIONAL RESIN: A CASE STUDY FOR Cu(II) REMOVAL

A comparative study on Cu2+ 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, solution pH and contact time. Ion exchange reaction showed a pH dependent feature. Maximum removal of Cu2+ 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. Thermodynamic parameters such as ?G°, ?S° and ?H° of the ion exchange Cu2+on cation exchange resins were also calculated. The regeneration performance of shallow shell technology (SST) resin is better than PFC 100. A solution of 2M H2SO4 performed complete regeneration of SST 60 resin. On the other hand, maximum regeneration reached 80% for PFC 100 resinA comparative study on Cu2+ removal by shallow shell resin (Purolite SST 60) and traditional strongly acidic cation exchange resin (Purolite PFC 100) was performed.
