Abstract: In this study it is intended decontaminate Cu2+ ion from drinking water. Simpe chromatrographic experiments were conducted with various solid matrices such as iminodiacetic acid (IDA) gel and various IDA membranes such as Sartobind and Convective Interactive Media (CIM) disk. Elution conditions and flow rate were optimized for better performance of the separation process. It is clear from these studies that the membranes do have larger binding capacity of Cu2+ ion over the gel under similar conditions. Also, membranes are easier to operate than the gel. Finally, affinity constant, KD, between the Cu2+ ion and the IDA gel was determined using Langmuir absorption isotherm. This study proved that the drinking water containing Cu2+ ion even at lower concentration such as 10 ppm could be decontaminated by theses solid matrices.
