Summary

Salinity and lowtemperature effects on adsorption of contaminant metals from water using an iminodiacetic acid (IDA) ion-exchange resin, were investigated under dynamic flow conditions. The order of selectivity of the resin (20°C and 0% seawater) was: Cu2+Pb2+Cr3+ Ni2+Cd2+Zn2+ Low temperature (4°C) had no significant effect on the selectivity of the contaminant metals and salinity only affected selectivity for Cr3+ and Cu2+. Copper had highest selectivity in all column experiments, except where extensive deprotonation occured. Buffering affected retention of Cr3+; possibly due to precipitation or complexation as a result of increase in pH.
