Adsorption process kinetics study showed the possibility of using egg shell as a natural adsorbent, and this has had a high effectiveness in eliminating ions of Cu ion from water solution. The experiments were conducted in a temperature range of 293 - 323 K, with the initial concentration of Cu ions of 5 mg/L and adsorbent of 5 mg/L. At during in experiments, pH Solution value was set to 6, and the amount of absorbed ions was determined the following time interactions: 10, 30, 40, 60, and 120 minutes. The experiments were conducted in an electric shaker, at 200 rpm speed.

The data the pseudo-second row model depends on the value of the correlation coefficient (R2), The results data suggest that this model describes the adsorption system well when the correlation coefficient R2 > 0.900. which indicates that this model is more applicable and better describes the examined adsorption processes in this study and speed of interacting with adsorbent and active places present on the surface of the biosphere.
