| Abstract: | Abstract Salinity and low temperature 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. |
