An ion exchange column containing 99.3 g of amberlite ion exchange resin was used to remove Cu2+ from a solution where Co = 0.452 M CuSO4. The tower height = 30.5 cm and diameter =2.59 cm. The flow rate was 1.37 cm3 solution/s to the tower. The breakthrough data are shown below:

Time (s)                               C [ Cu mol g]/L

420                                         0

480                                    0.0033

510                                      0.0075

540                                       0.0157

600                                         0.0527

660                                           0.1063

720                                            0.1433

780                                           0.1634

810                                              0.1722

870                                              0.1763

900                                               0.180

The concentration at desired breakthrough is C/Co = 0.010.
